Hello all!
I wanted to ask about my Bassman 70. It is still in the original Silverface specs so I thought to upgrade it a bit as I have done to my Fender Silverface Twin. My idea is to alter the phase inverter to blackface specs and to change the bias to a blackface bias next to normal ELCO and tube replacement.
Now I was wondering; the unit is rated at 70W (hence the 70 in the name)...... does this require a special bias / bias setting? As a 6L6GC is rated at 30W max you could'nt reach the 70W specs, right?
