WW2 Canadian Wireless Valve Testers

[Bruce MacMillan]

I do have a supplemental chart for the TV7 with reference to using the ED adaptor. It lists the settings for the CV # of the tube so a cross reference is needed. For example ARP4 is a CV1322. List is here:

Bruce.

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

Thanks,

David

[Bruce MacMillan]

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.
