Ensoniq ESQ-1 SN ESQ-31725-D



via this auction

"This is the plastic-body variety, which is allegedly more reliable than the earlier metal-body version. It has been professionally serviced and works perfectly. All filters tune correctly - see photo. I also replaced the internal battery, and updated the OS to the latest V3.5.

Stuff done:

New 2/3AA battery fitted. The proper OEM one, not a button cell.
Power supply completely rebuilt.
Tested and tuned and ready to go!
Replaced a few keys.
Keymapper IC replace.
There are minor blemishes on the front panel - see photos - but nothing major, and nothing on the display.
These instruments really sound glorious and are now starting to appreciate in value. Grab this one while you can!"
