Default Re: Mullard Valve Tester Card Project

Quote:
Did any of the early Mullard lists show the "EFM1/EFM11" Combined a.f. pentode/magic–eye tuning indicator, or did Mullard assume this valve had gone completely before the H.S.V.T. was designed, and therefore saw no need to produce a card set for it?
I have never seen this so have no card refernece for those valves.

Some magic–eye cards were marked with the "mixer–osc" test function I believe,
Which ones? I have not found one like that yet.
As prevously stated, the "TEST" field on the card is used to distinguish multi-card tests. It is blank on single cards.
