Repair Korg PS3200 Vintage Analog Synthesizer
This Korg PS3200 Vintage Analog Synthesizer had some serious issues. The PS-3200 is a semi-modular synth. Basically two PS-3100 synths in one enclosure and featuring 16 addressable and recallable memory locations for patch settings. It has two oscillators for each key and 48 notes of full polyphony! Each VCO module has its own VCF and LFO too! First I noticed, that one of the voices was dead. One culprit was a bad 6-stage divider chip which, unfortunately, isn't available anymore, except as NOS or replacement from flatkeys.co.uk.
All edge connectors were fine luckily. I just cleaned the contacts. I also re-capped the psu, renewed the heatsink, replaced the didoes. Re-calibrated the voltages. After calibration procedure, fixing some more issuses, I start to implement a KENTON MIDI kit to the Korg PS3200 Vintage Analog Synthesizer.
I’m documenting repairs for my reference and yours.
