Oh boy! What the heck did I just do? It's not in perfect shape, but I think I'll get it close by the time I'm all done. 1967 Supro Thunderbolt S6420. The original Tolex was the sexy blue. The new Tolex is just OK, a little amateurish. The output transformer has been replaced with a period correct, but not model specific replacement. The tone is fantastic, but not quiet at idle. All of that will be taken care of fairly soon. It's at the tech shop right now and I've got a line on an original cabinet in sexy blue that's in good shape.
