1st thing to check is the +/- 12 Volt DC supply lines on the CEM part pins 12 and 7...the TLO84 part , pins 14 and 7. They should measure from 11.4 to 12.4 VDC.
I would also check for cracks or loose jacks in the output PC board. I see that a LOT in repairs I do

I picked up an Ensoniq ESQ1 the other day that has very low output in
the left/mono channel and no output from the right channel. The ESQ1
Hacker page suggests that replacing the capacitors in the power supply
could cure many problems. The internal battery warning comes on after
power up, although it still has enough juice to hold patches so far
(after it was initialized). Looking for any advice/suggestions on
troubleshooting this. Thanks, Scott
