wondering if anyone has schematic on T25061GY RCA or if know of trouble that causes complete loss of audio. Output ok and can inject signal through it and mute circuit appears to be working ok also. No audio from tape or tuner. On Q4101 which shows to be audio amp on board has no or very low voltage to col and don't believe this should be normal but can't seem to track it through the circuits without some help. Thanks for any input. Dave Routson (Dave's TV) Help make your TechAssist online repair tips database better!
