Hello there... I have slowly been restoring an old Allen and Heath System 8 16:8 mixer. I bought it for cheap to learn/practice some repair work. I have been making some headway and the board is almost up and running. It's been a great learning experience thus far. There are still a few things I cant seem to figure out that will probably be a no-brainer for lots of you.
The first is that there is a wind-like sound coming out of the monitor outs. It is very random and sounds almost exactly like a breeze blowing out of my monitors... Strange. Any suggestions?
I recapped some of the board so far. I have done the right and left channels, the buss section and the 16th input channel. Everything works fine except for the eq section of the 16th input channel. I believe it worked well before, but I am not positive. When you turn the high or mid knob past 12 o'clock, a crazy feedback happens. It happens even with no signal passing through the channel. Some sort of oscillation. What could be causing this. I am worried if I recap other channels the same problem will occur. Any ideas on what I might do to fix this...
As always, thanks for your time. Cheers, Tj.
