Ready made plug & play Solid-State Vibrator replacements

solid-state vibrator pcb

Completed solid-state vibrator kit PCB, small
enough to fit inside an original vibrator.

To further our group project of selling solid-state vibrator replacements to everyone at cost price, I am pleased to inform everyone that we can now provide a complete ready made 4 pin sold-state vibrator in 6 volts, 12 volts and 24 volts. Also available are 8 pin (Octal) synchronous vibrators for Larkspur equipment such as R210, R216, B45, B47, B48, C13 etc.....!

If you are ordering one of our new solid-state vibrators for a C13, please make sure you tell us when ordering that it is for a C13 because these are not the same solid-state vibrators used in other Larkspur radios.

If you are unsure about what solid-state vibrator will work in your equipment, please e-mail us wireless-set-no19+owner(at)groups.io with the details of your equipment telling us the make, model and if possible any circuit diagrams and we will tell you if we can supply you with a replacement solid-state vibrator.

These new ready made solid-state vibrator replacements will all work on negative ground equipment. They are a direct plug in replacement for the old mechanical vibrators and will out perform the old mechanical vibrators in many ways. They have the same 4 pin or 8 pin plug on the bottom as the old mechanical vibrators have, so they will just plug in and replace most old mechanical vibrator with no modifications to the radio/equipment. If you are unsure about what solid-state vibrator will work in your equipment, please e-mail us wireless-set-no19+owner(at)groups.io with the details of your equipment telling us the make, model and if possible any circuit diagrams and we will tell you if we can supply you with a replacement solid-state vibrator.

Here are just some reasons for using the solid-state vibrator replacements;

1. No mechanical buzzing any more. This is great news for R209 users where the mechanical vibrations have been known to modulate the BFO causing a poor CW note and difficulty in tuning in SSB.

2. No interference anymore from the sparks across the vibrator contacts. These new vibrators are all solid-state, no sparks = no interference from the vibrator!

3. The contact resistance of the old mechanical vibrators can be considerably higher than the solid-state vibrator replacements, the solid-state vibrator replacements have an on resistance of under 0.008 ohms, that's less than 8 milli ohms.

4. Due to the much lower on resistance of the solid-state vibrator replacements, the HT regulation can be much improved. The HT voltage will dip much less when using a solid-state vibrator replacements than it will using an old mechanical vibrator who's contacts may have a much higher resistance than 0.008 ohms.

If you wish to use our solid-state vibrators to replace an original heavy duty mechanical vibrator you should have no problems. As standard the FETs used in our solid-state vibrators will handle 110 amps, so I very much doubt if any equipment will come even close to that kind of load!

The completely finished, ready to plug in and use, solid-state vibrators in 6 volt, 12 volt, and 24 volt, 4 pin non-synchronous cost only GBP 30.99 plus postage to anywhere in the world.

The completely finished, ready to plug in and use, solid-state vibrators in 6 volt, 12 volt, and 24 volt, 8 pin synchronous cost only GBP 32.99 plus postage to anywhere in the world.

For the first 12 months, if it fails I'll repair it FOC. - (The seal on the vibrator case must still be intact and unopened.)

If you blow it up any time within the first 12 months, I'll repair it for the cost of postage.
(Provided you haven't completely melted the outer case or the 4 pin plug on the bottom and the seal on the vibrator case must still be intact and unopened.)

If you blow it up after 12 months, I'll repair it for the cost of parts and postage.
(Provided you haven't completely melted the outer case or the 4 pin plug on the bottom and the seal on the vibrator case must still be intact and unopened.)

Kits, PCBs & ready made PCB details and prices.

The kit comes as a 6 volt, 12 volt or 24 volt version and will directly replace both a shunt fed and series fed -VE ground mechanical vibrator. Please note that these electronic vibrators are suitable for negative ground equipment only.

The kits are;

6v/12v/24v volt kit with the PCB, all PCB mounted components, instructions on building the kit and how to connect the PCB to either an original vibrator base/case or direct to the bottom of a vibrator socket of the equipment. All components are through hole, no fiddly surface mount, if you can use a soldering iron you can build the kits.

There are no modifications required to the equipment you intend using the sold-state vibrator in. The solid-state vibrator is a direct plug in replacement for the old mechanical series or shunt fed -VE ground vibrators.

The person building the kit will need to supply their own vibrator case/enclosure. The PCB will fit inside an original old mechanical vibrator can, this will ensure that the solid-state vibrator looks (and works) just like the original vibrator.

The cost of either a 6 volt or 12 volt or 24 volt kit, including all PCB mounted components and instructions, is only GBP 16.99 + postage world wide.

At a small cost we will build your solid-state vibrator for you and test it. Cost GBP 5.00 + cost of kit and postage world wide.

We can also offer a build service to incorporate the solid-state vibrator in to your vibrator case for you, this will involve you buying the kit, paying the fee for us to build the kit, you posting us your dead 4 pin vibrator to us and we will open the vibrator case and fit the solid-state vibrator electronics. Test that it is all working and then post it all back to you. The vibrator case will be opened at the base and there may be tool marks where the case has been opened and closed, this is unavoidable and should be expected, but most vibrators can be opened/resealed and most cases almost cases it is indistinguishable to an unopened vibrator case.

The cost of this service is GBP 36.99 for which ever kit you require + postage to you world wide.
This price includes the cost of us building the kit for you, opening up your vibrator case that you send us, installing the electronics into your vibrator case and testing it. You receive your vibrator back fully working, tested and ready to plug in to your equipment.

We can also offer to make your solid-state ready made vibrator buzz just like an original vibrator. This option uses a Piezoelectric plate to create the sound.
This option costs GBP 4.99 added to the cost of your ready made solid-state vibrator, we only have a limited number of the Piezoelectric plates left.


Our sold-state vibrators has been tested on a number of pieces of WWII equipment and more modern equipment too. The sold-state vibrators will replace both shunt fed and series fed vibrators that use -VE ground, it can also be used to replace synchronous vibrators too with the addition of only 2 diodes.

It is not only the Wireless Set No. 19 that our solid-state vibrator kits and ready made solid-state vibrators can be used in, but all -VE ground equipment that uses a 4 pin or an 8 pin -VE ground vibrator.

From Andy Jackson G8JAC, 23rd March 2020;

Mallory Vibrator Type G650
EMER Tels A472 says it’s a 12 volt shunt-driven non-synchronous vibrator rated at 3 Amps. 
Coded as ZA4878 and also known as Vibrator No.4 so the British army used it for something, but the EMER doesn't say what. 
However, the EMER also says that the G650 is the non-sealed version of the Mallory G629C  ZA27012 also known as Vibrator No.4T which was used in the R206 receiver, the Wave Meter Class D No. 2 and various line equipments.
ZA4878 is also listed as equivalent to the Wright & Weaire NSB/12 which the RAF used as 10KB/909.

The solid-state vibrators run at the same frequency of 110 Hz as most mechanical vibrators, should you require a different switching frequency please let us know and we will supply your kit(s) at your required operating frequency at no extra cost. Should you require a different operating voltage than 6v, 12v, or 24v please let us know, we may well be able to supply you a solid-state unit to the voltage you require.

(Contact us to ask if your equipment can use one of our sold-state vibrators. wireless-set-no19+owner(at)groups.io )

If your equipment or power supply uses a vibrator, it is highly likely it will work and have improved performance with one of our solid-state vibrator kits or ready made solid-state vibrators. The use of one of our solid-state vibrators vs. an old mechanical vibrator; the HT will be more stable, the HT will not drop on load nearly as much as it does with a mechanical vibrator, this results in greater stability of your equipment. Why? Because there are no mechanical switch contacts to cause a voltage drop across, the sold-state vibrator uses state-of-the-art protected, high current, low on-resistance HEX FETs who's on resistance is less than 0.012 ohms (12 milli ohms), that's less than the contact resistance of even the best mechanical vibrator.

Our kits and ready made solid-state vibrators use only the highest quality components; Fibre glass PCBs that are tin plated not just bare copper tracks. All of the components used in our kits are sourced form reputable component dealers such as Farnell and RS Components.

For more information, feel free to contact us and we will answer any questions about the solid-state vibrators.

Payment for kits can be made via PayPal.
The kits are available from us to anywhere in the world, contact us to enquire.

Hi Keith,

You are the king.
You rock.
You know your stuff.
That vibrator
(for an AM-598A/U PSU) works excellent!!!!!
Thank you so much sir!!!!
I have been testing it for an hour now.
Talking to my daughter in her bedroom, she has a PRC-126.
1.2 WATTS out of my PRC-9.
Sounds fantastic.

I can't say enough. You really need to advertise more. May I use your name, post your web site and a description of what you did for me in the Army Radio page?

Sincerely,
Ben

Hi Keith,
The SS Vibs arrived yesterday.
It took all of 10 minutes to replace the old mechanical innards with the new PCBs and install it in the old car radio - works perfectly!
It's a very nicely designed product indeed.
Thanks for the help along the way.
I've got a lot of old cars so you will likely hear from me again.

Best, Joe.

Hello Keith,
The vibrator kit arrived sy.
Thank you for such a super service!

20-8-19

Hello Keith,
That is a very nice kit. I used the two extra diodes that you supplied to
replace the function of the second set of contacts in the vibrator. The
arrangement worked very well. I plugged the solid state vibrator in and my
Sun distributor testing machine is now operating.

Thanks again.
Bill

I completed repairs on my transmitter and the solid state vibrator is working perfectly.
I have restored a correct charging engine and now (thanks to the new vibrator) both tx and RX are working exactly as they were when new...with DC from two 6 volt car batteries. Very pleased with the vibrator so thank you very much.

Andy.

Thanks
Received this morning and tested on two  DY-88’s set to 12 volts. Very good results over the original vibrator E201 as the boost to receiver O/P was about 15-20% improvement with both the IC vibrators you sent.
Will get round to assembling the (kit) circuit board and try that.
The instructions are very clear (for the kit) so thanks for your help and I am very pleased so will make sure to keep your details for any future purchases.

regards
Kevin

Just arrived.
Works great. My Gonset is working like a charm.
Just in case you want to know, the old vibrator is a: ATR vibrator Type 1840.

Thanks.

Best regards
John

Hi, Keith.
Your solid-state vibrator got my old Radiomobile Type B amplifier working again.
I just purchased another operating  Radiomobile Type B amplifier, but I will probably be getting another solid-state vibrator from you for that amp also.
Kind regards,
James

Hi Keith,
The vibrators arrived & i now have a fully working DY-88  
Unreal how both the original vibrators were faulty, especially the spare one mounted inside.
I will install the one in my R210 soon, just watching out on ebay for a decent 24v power supply to run the set.
Regards,
Shaun

I installed your solid state vibrator (in my R210).
The receiver is now 99% more quiet than before.
Operation successful !

Thanks and regards, Jarne.

All received ok and working.
How nice to just switch the PSU on and it works !
Thanks again Cliff.

The noise floor of my R209 was very poor and frequency dependent. I had to
set up my power supply for a 13.4VDC input to achieve a specified 95VDC HT.
In addition the IF's where all over the place and required a complete realignment
and sweep in order to restore sensitivity and bandwidth symmetry spec. Tube testing
the entire line-up revealed that V8 had internal shorts and leakage problems.
The RF section was peaked and realigned.

However, the set struggled to reach its S/N ration spec on all bands.

Enter Keith and his line up of solid state replacements for the old mechanical units. I cannot
recommend these solid replacements highly enough, absolutely silent in operation, more efficient.
I had to supply 13.4VDC to the set to achieve a specified voltage of 95VDC using the old
mechanical unit. For the new solid state unit it breezed by with 12VDC and a specified
voltage of 97VDC!! The receiver noise floor dropped considerably.

The old R209 has a new lease of life.. mainly due to Keith's electronic vibrator and a complete
tune up to specifications.

5-1-18

Hello Keith,
It has arrived, I have installed it - and my R209 Mk 2 has now sprung back
into life! Resolving SSB signals is also now much easier - as you predicted.

Very many thanks and Merry Christmas

Mark

Hi, Keith,

Just wanted to inform; the 6 Volt solid state vibrator has been tried with my radio and it worked beautifully.
The job has not finished though. Radio has to be put/installed back into its place.
I hope this would be straightforward and it will be lovely to see it working in the car.

Thanks very much for producing such a rare product.

Regards,
Cem.

I just wanted to say that your solid-state vibrator turned up today and I was immediately impressed with the build quality. To my delight the unit plugged into the 1947 EKCO CR32 valve car radio I am currently restoring and fired straight up! It has been running beautifully on the bench for several hours now with no discernable heat build up and with vastly less RF interference.

Definitely one satisfied customer here!

All the best,

Dan.

Your 12V vibrator for my WS19 was fast delivered and I am very glad to inform you that it works fine.
No mechanical buzzing anymore and more important no more interference from the sparks across the vibrator contacts.
Furthermore, I get about 250V (HT1). Practically no HT voltage dip when I turn on the A set !
(with the mechanical vibrator I got about 300V (no load) and about 200V (under load).

Now it is a pleasure to tune in the radio !
A must for all WWII equipment collectors !

Keith, Great stuff.
I shall be recommending you to my colleagues if they require assistance in this regard.
Also I may require further items I'll let you know.
Thank you again,
Best Regards, Pete.

Kit received Monday thank you, found extra diodes all right, instructions look great, it went together perfectly.
The new one sounds much quieter, and the voltage is about 8-10 volts up on the old style one.

Regards,
Nick

Yesterday I received the 6V solid-state vibrator in good order.
This morning I checked it in my "new" Class D no 1 Wave meter and I am glad to inform you that everything works fine.
It is a miracle to measure a deviation of less than 2 kHz with this about 70 years old instrument !
The DC-current consumption also is roughly nominal: 1.2 A .

Hello everyone,
I have recently purchased some solid-state vibrators from Keith (The Wireless-Set-No19 Group) to give a bit of lease of life to various WW2 radios I have that work from DC batteries.
I believe the vibrators that Keith is building are better made and do work very well.

So if you have any valve old sets that you have put to one side due to suspected mechanical vibrator problems like I did, then give Keith a try and get it working again.

14-4-16 - Ready made 8 pin (Octal) Synchronous 24v vibrator

Hi Keith,

The R210 was given a good soak (test) with your (Octal Synchronous 24v) vibrator, it's working very well.
I decided to put my meter thermocouple on the case of the vibrator to see what temperature it got up to with the R210 receiver out of the case, if I remember it was about 38C.

Regards

Leighton

 

8-4-16

(I've) Been testing one of Keith's new (Octal Synchronous 24v) vibrators in my R210, much neater than my effort using an old 12v vibrator can and a 6146 valve base, working very well, set is rock steady on 5.505 MHz listening to Shannon Volmet ( USB ), been on about 2 hours, can is only slightly warm to the touch, I will leave this on for the day and check the set again to see if it has drifted.

Well done Keith !.

Built the solid state vibrator ...a nice kit....as the original vibrator is okay at the moment I will keep this as a back up ......
To do a quick test I ran it into two 47 ohms resistors in series with the center tap for the positive supply worked perfectly scope showed a nice square wave on either SW points..resistors got a tad warm of course.
A nice kit that worked first time great...thanks

Hello Keith,

Thank you very much for the package of vibrator kits, I am just now about to make a start on them.
I would congratulate you for taking the initiative and time to organise this project, as the power supplies are often the difficult part of running old military equipment.
Thanks and best regards

Richard.

24-11-14

Good afternoon Keith,
Just a note to confirm I have received the solid-state kits safely and well presented again.

I do hope that after my and other comments posted on the groups forum you are finding the interest the kits deserve. Anyway I'm delighted with them so will also enjoy making up the circuit boards as I need them, something I've not done for a long time!!

With best wishes and thanks for the hard work that's gone into this project,

Kind regards,

Alan.

12-11-14

Morning Keith,

The kits arrived this am Ė thanks very much.
Donít know when Iíll get around to building them, but not any time soon I think. They are more of a future investment.
Have to say that, as an ex-electronics bod, Iím quite impressed with your final product Ė neatly done and good documentation. Pat yourself on the back !

Best,
Mike

You ship your original unopened vibrator to us and we will open it, build our solid-state electronics in to it, seal it closed again, thoroughly test it and ship it back to you.
There may be small tool marks on the bottom of the vibrator's can where the can has been opened and closed again to install the solid-state vibrator electronics.

The original vibrator will be dismantled, the old mechanical parts removed and a modern solid-state
vibrator PCB fitted. The vibrator case is then resealed and our label added showing model of solid-state vibrator.

6 volt or 12 volt or 24 volt rebuild of your original vibrator in to a solid-state vibrator is only GBP 36.99 + postage.

We can supply 6 volt or 12 volt or 24 volt kits of parts for you to make and build in to your own vibrator. The kit contains the PCB and all PCB mounted components plus the diodes required for the synchronous rectifier part of the vibrator. There is also full instructions on building the PCB and connections to your vibrator. When ordering a kit you should specify the DC voltage you power the equipment from, not the original vibrator voltage and equipment you intend using the solid-state vibrator with.

6 volt or 12 volt or 24 volt solid-state vibrator kits with the diodes required
for the synchronous rectifier part of the vibrator are only GBP 17.99 + postage.

The solid-state replacements we sell out perform the old mechanical units in many ways;

1. Better regulated HT due to very low resistance FETs that are used (8 milli ohm, 0.008 ohms).

2. No interference anymore from the sparks across the vibrator contacts.
These new vibrators are all solid-state, no sparks = no interference from the vibrator!

Simply put, the new solid-state vibrators will out perform the old mechanical vibrators in every respect.
