"Tested and working perfectly.

This unit has been serviced extensively by vintage synth expert Steve Jones in Sydney.

Cosmetically the unit exhibits typical crazing and rust spots throughout but it sounds like a million bucks!

I would be very wary of buying a Jupiter 8 that has not been serviced by a real professional who has documented the work carried out. Parts are extremely expensive and difficult to find.

Below is the work that was carried out on the unit from the work order July 2016

'Located and replaced failed Roland BA6632 VCA on lower module controller board. This was killing the VCF LFO on lower voices. Cleaned up gain selector switch. Replaced failed CA3046 transistor array which killed voice 4 VCO 2. Replaced perished rubber buffers on the pitch bender. Calibrated bender and mod controls. Repaired dry solder joint on volume board that was silencing the upper output. Cleaned up all of the intermittent switches and controls'"
