I hope I never find a killer deal on one of those. Because I'd probably like it!
Don't look too hard, then. These amps are at the top of the "too heavy, too loud, too clean, not vintagey enough, and too hard to sell" list.
EDIT: There was a local guy selling off an STR that needed major repair and was non-working, I thought about for a project amp. I think it went sub $150. Not bad. But the thought of tube replacement was scary. That's a lot of tubes.
Note that there were two versions of this amp. The first one, the Super Twin, did not have reverb. The Super Twin Reverb shown in the ad obviously has reverb...and is the second version. I have owned one of the STR’s.....great sound. It did the best plug and play SRV tone I have ever heard. Nugent was a user......he played SIX Super ?Twin Reverbs with a 2x15 Dual .showman cab plugged into each ext spkr jack.....1080 watts coming out of 24 speakers. He played a hollow body Gibson Byrdland...solid maple back and wides with a hand carved spruce top...through this rig. The stage was marked so that he knew where the ‘hot spots’ were and weren’t!!! Feedback control, anyone??
if it was not working, then imho it was worth less than $100. If I can’t hear loud sounds..even bad as long as they are loud....I consider the worst case scenario, which would be replacement of one or both transformers.
