Kevin, based on what you've said here, I'd go for the TL922 and use the
audible tuning indicators to tune it carefully. For $450 it's a great deal,
and even if all the caps need replacement, it's still a good deal. The
AL811H is a cute and worthy amp but I don't think it will take sustained
tuneup time as well, and changing the 811A's to 572B's won't provide any
additional output power; that is limited by the HV supply.
