Yeah, I make my living in electronics, and learned it when I was a kid on the tube stuff. I worked for awhile at a place called Daddy's Junky Music in NH, as an electronics tech, and did alot of work restoring the old amps. Always my favorite stuff to work on.
Oh really? I just had the Supro, and the Twin Reverb gone over completely by a tech in Toronto that specializes in the old gear. The Silvertone on the bottom left is from 1961 and still has the original tubes and works fine!
