+1 on Terrance Slemmons. Great tech and awesome guy to deal with. I once had a Mesa 2:90 I bought on eBay from a seller in Puerto Rico arrive in really bad shape. the guy wrapped it in a single sheet of cellophane, placed it in an oversized light duty box...ugh. Had pots sheared off, broken switches, 1/4 thick steel face plate was bent to hell and warped. I replaced the tubes but it wasn't working. Took it to Slemmons and he not only repaired everything, he even fixed the cosmetics and front panel at no extra charge. Good guy.
