WW2 Canadian Wireless Valve Testers

Since this is going to be a free standing Adapter, I have decided to finish the case in a wrinkle black paint and the face panel in a gloss grey similar to the Stark original in Bruce’s Post # 6. I think that should give it a suitable vintage look.

I got one of these from a friend of mine today. Looks rusty but it is just a surface tarnish that should clean up OK and one set of original hardware is still attached that should be easy to match. He thought it would make a nice addition to the adapter project and I quite agree.

Found a very nice shade of high gloss grey paint today which should look appropriately vintage.

Should be able to get some preliminary work started on the case assembly in the next few days. Just a bit of careful work to get out of the way on my 52-Set Main receiver first.

A little bit more progress on this project over the holidays.

I have now mapped out, and drilled the holes in the adapter case for the connector cable assembly and the four rubber feet on the bottom. Next step will be painting the case a flat black primer. After it has cured, a coat of wrinkle black will be applied and allowed to cure.

Interesting about the British versus North American valve sockets. Right from the beginning of local military wireless production here ,around 1939, they decided to use the North American standard valve base configuration. Who made that decision I don't know .The 11 set (Aust ) and all of the other wartime built sets I've come across utilize the North American valve configuration.

The Adapter Case has now received a coat of Satin Flat Black Base. Once it has cured for a bit, the final Wrinkle Black will be applied.

I suspect that was a purely pragmatic decision. America is closer to Australia than England, there would be far less of a threat from enemy action (at least, initially), and England couldn't make enough wireless sets for its own use anyway.

There was almost cetainly existing commercial trade since the AWA manufactured version of the WS19 used the Australian (I assume) versions of the American valves rather than the UK/US market ones. (The usual "dominate your market by making your kit dependent on your own manufactured parts" trick.)

Hi

Yes that pretty well sums it up. The AWA 19 set was fitted with valves such as the ..6U7G as rf and if amps ..AWA made their own valves branded as AWV . I read an interesting article by a chap who worked at AWV , he described how they modified contemporary US made valves to suit the local Australian manufacturing conditions.


The little infantry 108 sets had those short squat GT series octal based valves
