"I'm sure it could be biased to run on EL-34 or 6550 though." Biased, possibly. Driven, probably not w/o major pre-driver/driver redesign. And then you wouldn't have the SA1000 any longer.

The 8417 was the last of the consumer grade 100W power tubes released. It combined the power capabilities of the 6550 with the extraordinarily easy drive requirements of the 7591. Actually, in all important respects, the 8417 is equal to two 7591s in parallel but with somewhat greater voltage capabilities. IIRC, Fisher advertised that the 8417 was originally created for this specific amp but a few other mfgrs used it too. Both GE and Sylvania mfgd them but the Sylvanias were best by far. GEs had a tendency to run away at the slightest provocation. Guess which version is unobtainium.
