[QUOTE="charles, post: 1069176, member: 2759"] The "super" Brimar 33A/101K (12AT7) double triode and the AVO valve tester Found some Brimar 33A/101K NOS valves. Took me some time to find out what this valve really is. The box: The box is much bigger than the ordinary box for these type of valves. The valve is secured in an innovative method in the box. One one side is a printed indicator, when replacing the valve in equipment. The valve: Beneath its number is a neat acid marking. This number appears in the AVO valve data manual and its settings is the same as for an ECC 83 valve. This is not correct: [b]The correct setting is as for an ECC 81 (12AT7)[/b] [/QUOTE]
