I paid up for this one and the beautiful mid century wood cabinet is sitting in my trash right now. Got lucky and unlucky. Got a pair of telefunken 12ax7 and westinghouse 7591 output tubes, that's a score. Also got 4 more rca 12ax7a tubes, not worth much, but nice having them laying around. The woofers bring $50 or so on ebay. The unlucky, i was hoping the amp was a self contained unit, it is not, it is a monstrosity. 18" x 50", point to point wired for 60 tubes, it truly is an industrial work of art (i will get pictures). So, no "project amp" without a lot of custom work. Bet it would sound good, 12ax7 and 7591 output tubes with a 12 lbs transformer (it's big).
