So it's the ~<$500 range and 50-75wpc still, right?

For power amps:

Perhaps look around for a used Bryston 2b (or 2blp?) 60wpc. 20y warranty. Piece of mind for you, given the scenario presented.
Get the serial, call bryston, see how many years are left on it (and that it is a valid serial etc.). On some of the newer stuff, they are wanting to see receipts iirc (to ensure bought from a proper reseller) - so check out that situation before commiting as well.

Note there are 2 or 3 (2 original, and 1 of the new model?) versions of the 2B.
Look at the rear connections and for presence (or not) of front volume controls, in order to know what you are looking at. (though, seems they will mod them if you send them in).

Were you in NY? If so, may even be able to drive/drop for service. I think their US service center is up there.


Crown D45, D60, D75a et al could also be considered, and (I think) still bought new... but I think they hiked the prices way up when Harman (harmen, whatever... ) bought them out. Maybe trying to kill off crown that way.

* Personally, ~8w from a 6BQ5 Almarro A205 I got in trade, is too much for me. If considering modern tubes, you could also have a look at them.
