Ready made plug & play Solid-State Vibrator replacements (pictured above)

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 now are 8 pin (Octal) synchronous vibrators for Larkspur equipment such as R210, R216, B45, B47, B48 and the C13..!

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)yahoogroups.com 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)yahoogroups.com 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 and 8 pin synchronous, all cost only
GBP 29.99 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 or just the PCB 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;

1. Just the PCB itself where you fit your own components. It comes with full instructions for building for both 6 volt, 12 volt and 24 volt versions of the solid-state replacement vibrator.

2. Six volt kit with the PCB and includes 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.

3. Twelve volt kit with the PCB and includes 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.

4. Twenty four volt kit with the PCB and includes 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.

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 the PCB and instructions on its own is only GBP 5.99 + postage world wide.

The cost of either a 6 volt or 12 volt or 24 volt kit, including all PCB mounted components and instructions, is only GBP 14.99 + 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 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 case will be opened at the base by unrolling the aluminium edge and rolling it back afterwards. There will be tool marks around the rolled edge where the case has been opened and closed, this is unavoidable and should be expected.
The cost of this service is GBP 15.00 + GBP 14.99 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.

The sold-state vibrator has been tested on a number of pieces of WWII equipment and more modern equipment too. The sold-state vibrator 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, but all -VE ground radios using a 4 pin -VE ground vibrator, this includes, but is not exclusive to; WS19 WS22, WS C12, WS38 AFV, WS88 AFV, WS31 AFV, R109, R209 Mk1, R209 Mk2, R209 Mk2/B, R210, Class D Wave Meter No. 1, Class D Wave Meter No. 2, New Zealand ZC1, GRC-9 in the DY-88 PSU (*) and WS52 Remote Receiver. Pye Dolphin Mk 3 Marine Radio Telephone (12 volt and 24 volt versions).

(*) This uses a synchronous vibrator and by adding only 2 diodes our kit can be used to replace -ve ground synchronous vibrators too.

 

Our ready made solid-state Vibrators have been confirmed as direct replacements for the following;

It has been confirmed that our 12 volt 4 pin non-synchronous solid-state vibrator is a direct plug in replacement for the Plessey 121HD4, 12 volt mechanical vibrator that is used in many pieces of equipment including the Pye FM Ranger PTC8002.

It has been confirmed that our 6 volt 4 pin non-synchronous solid-state vibrator is a direct plug in replacement for the Mallory 294, 6 volt 4 pin vibrator.

It has been confirmed that our 24 volt 4 pin non-synchronous solid-state vibrator is a direct plug in replacement for the Mallory M650C, 24 volt 4 pin vibrator.

It has been confirmed that our 12 volt 4 pin non-synchronous solid-state vibrator is a direct plug in replacement for the Plessey Type 1214 12 volt 4 pin vibrator.

 

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)yahoogroups.com )

If your radio or power supply uses a 4 pin vibrator, it is highly likely it will work and have improved performance with one of our solid-state vibrator kits. 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 MOS 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 use only the highest quality components; Fibreglass 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 vibrator kits.
Payment for kits can be made via PayPal or cheque/postal order within the UK.
The kits are available from us to anywhere in the world, contact us to enquire

Hi Keith,
Your kit arrived this morning as you predicted. It's now built and Class D wavemeter is working fine.
Many thanks for helping me out and prompt supply of your superb 6 volt solid state vibrator.

Regards
Dave

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 Wavemeter 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 .

Best regards,
Frans

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

(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 centre 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

Just had the capacitor across the transformer secondary go short
circuit (0.1u 1KV), blew a 10 A slow blow primary fuse several times in
finding fault, the FETs in the solid-state vibrator survived GOOD DESIGN!

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.

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

GRC-9 Solid-state vibrator Replacements.(DY-88 PSU)
 

Give your GRC-9 a new lease of life with a state of the art solid-state vibrator

This is a complete solid-state replacement vibrator for use in the DY-88 PSU.

This is a ready made plug and play replacement for your old vintage
mechanical power supply vibrator in your GRC-9's DY-88 PSU.

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.

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

We are able to offer a small number of original mechanical GRC-9 vibrators for the DY-88 PSU
as well as solid-state GRC-9 vibrators for the DY-88 PSU.

Original mechanical tested and working vibrators are GBP 25.00 + postage.

Complete, built and tested solid-state vibrators are only GBP 34.99 + postage.

Please note that these are original vibrators, some of the original vibrators I have are a slightly different colour, but are
truly original vibrators that I have opened and fitted the solid-state vibrator electronics in to and resealed the case.

The vibrator cans have NOT been cut open, the bottom edge has been unrolled and rolled back closed again to seal the can.
There will be tool marks on the underside of the vibrator's can where the can has been opened and closed again to install the solid-state vibrator electronics.
