So what happens to the noise, assuming you can meter it somehow, if you
either locally squirt freezer spray or warm with hot air, individual op-amps

i'm in the cleaning process, so, as each module is separated, i have mounted 2 channels, 2 buses an the master fader (cleaned).

For now, what i can hear is some "white" noise without any gain or fader level, juste the mixer powered on.

by selecting mic source and pushing master fader, i'm getting some hum with nothing plugged in.

my headphone left channel is completly distorded, and changing the scorched resistor had effect..

well, i'm a bit dispponted just now, but i will clean the rest of the channels and give it some more try. just don't know what to do to "fix" things so i'll go step by step... (oh baby)
