Need help with xr600c with 400BH amp
My amp died after using it every week for years. Just went dead. I tested the voltages and all seems good so I hooked up a speaker and slowly brought it up with a 200hz 1.5 mv signal on the input pin of the amp board. I got to about 60V in drawing ~.25A and started hearing the 200hz. As I increased the line voltage the speaker pulled down hard so I shut it down. When I give it full line voltage with no load I see no DC on the speaker jack. Does anyone know what this could mean?

Amps are not stable at low voltages.
