I have this amp that my dad bought in 1983, i t is a peavey and the name is audition 20. i was wondering if it is a tube amp.(ill pictures uploaded pretty soon)Plz tell any info on this amp.
guessing by this, I am guessing it is not. Check the back if there is a slot for something, than it might be.

But if the back is solid and has nothing but power chords coming out, than it is not.
top axes:
Taylor GS8
Fender American Strat (w/DiMarzio pickups)
Epiphone Les Paul
