Ensoniq SQ-80 Strange Problems - Please Help

[AwakeFM]

Thanks for the reply Sam! I found that thread:

Ensoniq ESQ-1 Filter Tuning zero and almost no sound

Hi everyone, I’ve got an Ensonic ESQ-1 that has a couple of problems. I’ve followed some advice found in the gearsluts forum, but so far without noticable improvement. So I hope to find some help here. First of all, it’s a metal Case ESQ-1 running OS3.5. The battery was dead but successfully replaced. There’s no output, or rather super low output (have to crank up the gain on the recording preamp really hard to hear some sounds), apart from the noise when switching it off, which is normal vol…

The issues do sound similar. It does make sense it’s a main board issue, as everything else seems to be working OK.

Any chance you have a functional main board in stock? That would be the most straightforward way to fix it I guess.

Thanks,
Chris
