I wasn't entirely happy with the behavior of 4CX1000A pulls, so I decided to bite the bullet and try a new tube. So much for my 'cheap' amplifier project (you hot rod guys understand the phenomenon o

Hello Vic, I just took delivery of a new Alpha 8410 amp about 3 weeks ago. Alpha said that they consider the two tubes interchangeable in their amps. They also said that either tube pair is way overk
