My Hickock manual for my 800 was changed to "24" for the bias on 6922.
Hickok 750 Tube Tester US vs. European Settings
I have a Hickok 750 tester. Do you know if I can use the same settings for all of the US and European 6DJ8 variants?
I have the whole gamut; 6922 7308, CCa, E88CC Ecc88, E188CC.
Same question for the 12A*7 variants.
Thx.
