  OK, maybe you've already done this, but if it was me and without a DVM, I'd be looking for components with burn marks - particularly resistors and diodes.

    Ive been checking like mad! Still stumped, though.
    Thanks for the info.
    I already gave a once-over to the resistors, but not the diodes. I'll double check them. Are there any diodes that are specific to one channel? I kinda thought the power supply was pretty much stereo, so i've ignored it. Could the soft start thing have two channels?

    Since I got my multimeter, ive checked just about everything I could think of ('cept the PS). None of the coupling caps were at fault, the OPTs look good, the last PS caps on both sides behave the same. AARGH! I'm starting to feel like I've missed something really dumb. Thanks again,
    saul

      What was the point of using 3uf interstage coupling caps? Don't those need to be kept low for good frequency response? I would double check the caps.

      Check corresponding voltages for each channel, starting with power supply @ the (2)47k parallel resistors. You should be able to find the trail.

      Foreplay not really a good match due to Ellas high sensitivity, alth

      Good luck, let us know what you find,

      Mark
