What’s wrong with your other thread asking basically the same thing a day ago?
agree
Use the force, Luke.
and this comes from a member that starts new threads all the time 😀
OP
you have started these posts and have mentioned that you use class A and A/B amps but not one time have you said what amps they are? don’t you think it would be helpful to mention what amps you use as i am sure a member(s) could them chime in with tube preamps that have used that were good or bad with the amps you have.
