JohnA Posted March 20, 2003 Share Posted March 20, 2003 Can a push-pull tube amp be Class A? How much power should an amp produce it is has 4 KT-88s and is run in Class A? Quote Link to comment Share on other sites More sharing options...
NOSValves Posted March 20, 2003 Share Posted March 20, 2003 Mark, What can a Mark III do in Class A with out using the tubes strapped in triode ? Craig Quote Link to comment Share on other sites More sharing options...
Deang Posted March 20, 2003 Share Posted March 20, 2003 I'm not about to cross swords with you Mark, but man, that number seems kind of high for a Quad of KT-88's in Class A. Doesn't it depend on the circuit (ultralinear, pentode, or triode)? I guess an A/B amp never really 'stays' in Class A. My Quicksilvers have 7 to 9 watts, but anytime the music asks for it -- it's going to go into Class B regardless. Playing around a watt or so, with Scalas -- and your probably going to stay in there pretty much. I'm going to guess the Dynacos give you between 7 and 12 watts.

Deang Posted March 20, 2003 Share Posted March 20, 2003 I sure as hell don't. Buy hey, you got Heritage dude -- you're never pulling more than a 1000th of a milliwatt no matter how far you turn the dial!! Heh (Kelly euphenism). Quote Link to comment Share on other sites More sharing options...

Deang Posted March 20, 2003 Share Posted March 20, 2003 Extremely busy at work, they're killing me. I read it, just ran out day to answer it. Thanks for the tubes! You and Edmond are nuts if you think you're ever getting all of these tubes back -- yeesh, I'm set for the next 10 years! Quote Link to comment Share on other sites More sharing options...

NOSValves Posted March 21, 2003 Share Posted March 21, 2003 Mark, Well I;m sure you have done the Class A route on the Mark III so what kind of output can be achieved in straight Class A Ultra linear output ? Craig Quote Link to comment Share on other sites More sharing options...
JohnA Posted March 21, 2003 Author Share Posted March 21, 2003 Can any of you explain how push-pull, which implies Class B to me, functions in Class A? Shouldn't they just be operated in parallel? Quote Link to comment Share on other sites More sharing options...
