No problem, just email us at wireless-set-no19+owner(at)groups.io with the answers to the following questions;
 
arrow
1. what equipment is the solid-state vibrator or kit to be used in?
2. what DC voltage is the equipment connected to, 6v, 12v, 24v?
3. how many pins does your original vibrator have?
4. do you know the manufacturers name, part number and voltage of your original vibrator?

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.

Our ready made negative and positive ground solid-state vibrator replacements will all work on negative or positive ground equipment as appropriate. 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.


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.

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 115 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
I received the 3 circuits (6v, 12v & 24v kits) this afternoon, everything is mounted, integrated in original cases and fully operational.
The 3 are delivering the same voltage to the radio.
It's great!
Thank you very much
François

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.

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

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,

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

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 .

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.

From S.D. Fowler G0TGM

 

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

(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

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.

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

Keith,
Just to let you know my 6v unit is now powering my Mk 1 R209 very happily, no annoying background vibrator buzz now.

Thanks for your efforts,
Gordon.

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

New triple voltage ready-made, kits and pre-built kits are now available for your DY-88.

Vibvib

Replacement 7 pin vibrator for use in the DY-88 PSU.

We have reached point in our supplies of the original 7 pin vibrators that we have only two original vibrator left .

Our remaining original solid-state vibrators now use our latest triple voltage technology so that the solid-state vibrators work exactly how the original vibrator worked. You simply plug the new solid-state vibrator in to your DY-88 and set the DY-88 voltage selector switch to what ever voltage you wish to power the DY-88 from and that's it. One solid-state vibrator does all voltages that the DY-88 does without changing vibrators.
We can offer these last two ready made solid-state vibrators for
GBP 46.99 each + shipping world wide.

We can offer to rebuild your original 6 pin or 7 pin DY-88 (GRC-9) vibrator, making it in to a solid-state vibrator.
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.

This is done using our latest triple voltage technology solid-state vibrator PCB, this means your rebuilt solid-state vibrator will work in your DY-88 with the DY-88 set to 6 volts or 12 volts or 24 volts, this rebuild of your original vibrator in to a solid-state vibrator is only GBP 36.99 + shipping world wide.

We can supply our latest triple voltage technology solid-state vibrator kit 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. Note that you will have to set the frequency of the PCB to 115 Hz using an oscilloscope, this is simple enough to do and the instructions show you how.
The kit costs GBP 18.99 + shipping world-wide.

If you would like one of our latest triple voltage technology PCBs ready-made, setup and tested for you to put in your DY-88 vibrator, for only GBP 23.99 + shipping world wide.

The switching FETs in the above photo are covered with heat shrink to insulate them.
The FETs do not require a heat sink because they do not get warm at all, but their tabs should
not be allowed to come in to contact with anything including each other.

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.
