repaired!
I just want to close this string by reporting to all interested that I repaired this sucker, finally. The bad components were as follows:R2,Q4, and R17 through R22 were all high values, but not completely open. None of these components showed external signs of damage, which is weird.
The Dc outputs are now all correct, with only .06 VAC of ripple.
the only slight concern i have now is that there is a hum coming from the supply, it seems to be around 60 Hz, and seems to be coming from R15, which is a % watt power resistor, or a transformer. Is this normal for a switching power supply? Should I be concerned? i have heard hum from power supplies before, but I want to be 100% certain everything is OK.
Thanks again for the good advice in getting this thing fixed!
