WW2 Canadian Wireless Valve Testers

[David Dunlop]

Bruce.

When you have a chance, can you post the dimensions of that valve adapter box?

Thanks,

David

It's 6.5" L X 2.5" W X 1" D. Mounting frame is attached to the lid.

Thanks for the measurements and photos, Bruce.

I have a 2-1/8” slot at the top of my Precision Tube Tester used to stow the cables. I should be able to use it to store a free standing version of this adapter quite nicely.

Trying to decide now whether to use an 8 conductor cable very similar to the one on your set, or a brown cloth loomed equivalent that looks like the Remote Supply Connector cable for the ZE-11 and ZE-12 52-Set Supply. Will probably pick up a length of each to see which is more flexible to work with.

Cheers for now,

David

I have the valve sockets for you, the only difference is that the B7 one is one piece moulded bakelite (i.e. does not have a metal mounting ring), the others are as per Bruce's photograph.

Octal plug is proving difficult - I've found chassis-mount ones (like a reverse valve socket) both with and without the metal mounting plate, but not a cable mounting type.

There's also the WS 52 connector - you'll need a thin 1/4" AF socket to remove the nuts holding the contact springs. (o.d. less than 0.38" to clear the recesses in the socket.)

I'll see if I can get them in the post tomorrow.

Chris.

Thanks, Chris. Your help is very much appreciated.

I have found a potential source for the octal plug in the States. They carry them with clip on covers with a metal grommeted hole in the end for the cable to pass through. Just waiting to see if they have the ones like Bruce’s photo, with the metal cable clip which I think serves as an anti strain devise for the cable.

Will let you know what I find out.

Best regards,

David

An hour's worth of driving South this morning was a very worthwhile trip. It took me to Pembina, North Dakota and my favourite Parcel Service Shop where I was able to pick up some pieces for the British Valves Adapter I will be building this Winter.

I had found a suitable sized enclosure locally on Saturday to officially start things off. Todays trip produced a three foot length of brown cloth loomed 8-Conductor Cable for the project, along with a pair of Octal Plugs and a metal Plug Cover with a metal cable anti-strain fitting as per the photos Bruce posted earlier on this thread. All of this from Radio Daze out on the East Coast of the USA.

One more request, Bruce.

Can you give me the diameters of the four holes punched in the cover to mount the sockets? It looks like the two inner ones are the smallest and, perhaps identical.

I thought the two larger outer holes might both be identical to each other, but a closer look suggests one of the outer holes might be larger than the other.

I have a set of socket hole punches, but can also access an adjustable cutter if I need it.

Factor in possible socket variations among manufacturers and this part of the project becomes interesting very quickly.

Best regards,

David
