Budget/value SS power amp recommendation


Hello all would appreciate any recommendations for a budget solid state power amp for a lightly used 3rd system to pair with some tube preamps. Budget is less than $500. New, used , cosmetics irrelevant. Initial thoughts are the following but don’t know if they obtainable on this budget.

Any thoughts or suggestions welcome. Would love to find a sleeper under the radar model or something discounted if it’s cosemticlaly challenged . Thanks

Still running a GFA-5500 as my back up. It never lets me down and (with a long warm up) it always sounds good.
Also a big + for the B&K....Jim
