so do any of you guys ever shop the vintage electronics section of ebay? just there yesterday and there are loads of tube amps for not so much. i got an old one off there- manufactured for a movie projector actually- that just with my geb-7 and bass can really growl. i'm thinking my next amp might be a 50 or so watt metal box that looks like it fell off sputnik-- rust, dents and all. just have the local wizard stack all of the input preamps together? thoughts?
