Ensoniq ESQ1 low output

2008-03-23 by Scott Davies

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
