TFT 884 Mod Monitor

H

HadYourPhil

I have one of these with an odd problem. The audio monitor and meters are dead but the peak flasher and peak calibration work fine. Meters don't move and there is no audio at the headphone jack or rear terminals. The schematic is somewhat confusing and unfortunately smudged a bit and the labelling is unclear, too. There are no signs of trauma. Any ideas? TFT is long gone, right?
 
It's been 30+ years since I have dealt with TFT, but I would check the output of the power supplies on the board just because "unrelated" functions are affected. Also check out steampoweredradio.com they might be able to help you.
