AA864 Bassman // First inClass BF Tone ?!

This amp came in after it started to smoke – both Screen blockers where fried right open … power tubes toast

A new set of GT-6L6GE’s, new PSU filter caps, new power socket resistors, and a re-biasing later and she was good to go. Probably my fave for tone in the Black Face line, the AA864 Bassman sounds especially killer with KT66’s // but that’s another story!
