I have a Seeburg model 220 with the SHFA1 stereo amp. Lately, the sound has changed: the vocals seem VERY weak. It does not appear to be one channel - they both sound the same: you can hear the insturments fine, but the vocals on all the records sound almost muted in comparision.

Is this a bad tube, and if so, which one ? Thanks - Mark
