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
