A friend of mine just bought a 1983 JCM800, and he wants to put KT-88's in the power section, so we opened the chassis and discovered two el_34's. The question is: Has the circuit been changed to accomodate el34's as opposed to 6550's? Or is it just a bias issue? Also, are there any simple mod's he can do when putting in the kt-88's?
Any replies would be appreciated greatly.
