Re: Mullard Valve Tester Card Project
That list of unissued cards is interesting in being a little short of previous lists.
Needless to say it is now known that the unissued cards do exist, well some of them at least. They tend to show up in the military cards, so if anyone has one of these then please check.
I would be interested to see a valve list that says what is tested by some of the previously thought to be unissued cards.
