WW2 Canadian Wireless Valve Testers

[David Dunlop]

Hello Bruce.

Any chance you could post some photos and specs for that adapter?

I poked around the net a bit last evening and quite a few adapters turned up. Most, however, were single tube types (or sets of same) with little or no information as to what was being adapted. A lot of them also seemed to be for the later postwar miniature style all glass valves to be accommodated in older test equipment.

A few caught my eye as being small square or rectangular metal boxes fitted with four or more sockets and a long cord. The end of the cord had a base plug on it that likely fitted a common socket on most testers. Again, no information to be found on what tubes were being accommodated. Be nice to find an “ XYZ Company, Model 123” that was identified as being for the British tubes to be tested on North American equipment and supporting documentation.

While I think of it, did the massive import of wireless equipment from North America during the war create a similar, reverse, problem in England I wonder?
