Hi folks,
I came downstairs this morning and fired my st-70s up and one flashed and blew the fuse. I replaced the fuse and turned the amp back on and I get zero bias voltage on all 4 output tubes. All tubes still light up, but there is no sound in either channel and no bias voltage. Please tell me this is something simple.
