Default Re: Mullard Valve Tester Card Project

See http://air-ministry.uk/mullard.htm for how far I got, which is close to all the known cards. But to confuse matters the odd card outside the documented range turned up which raised the question as to what they were for.

I have been meaning to try a final big push to get the last few as rumours keep circulating that some people have all the cards. But I have not managed to meet them yet!
