Re: Mullard Valve Tester Card Project
The CV cards are just differently presented versions of the commercial cards. It was just that they were stored indexed by valve instead of by card number, thus making it a little faster to use (and no lookup list to loose). So just look to see if you have any that are in my list of missing cards.
Card 227 is interesting. I have encountered a number of these, but so far the thing that I don't know is what valve it tests - so do you have that information?
