Yes the 6CG7 family is a wonderful tube type. Got to be careful if you are not using it as a driver however. I would never put a 6CG7/6FQ7 in a highly sensitive application. Same for 12BH7s,
6922 Tube Question
I need to replace a pair of tubes in my VAC Signature. They are 6DJ8 6922's. Though I've had tubed pre-amps for years, this is my first tube replacement. So I have a real newbie question. Are all 6922's interchangeable? Can I use any 6922 or must they be 6DJ8 6922's?
ps - ya, I know, bad time to need tubes given the world situation.
