It was part of a big collection of mostly tube gear that I bought a year and a half ago from the daughter of a guy who died suddenly. He left almost no information behind about his collection so it has been a "inspect, test and see what it needs" process for each piece.
This Bogen 230A needed very little. I tested all of the tubes and brought it up slowly on a variac while measuring PS voltages and it played music. One output stage coupling cap measured a bit off so I changed them all to be safe. Other than that, I cleaned the controls, adjusted the output stage and that was that.
Whatever you did was just enough and not too much. Forever thankful.
