"Due for original voice chip cleaning or replacement which is normal for these classics and also reflected in the price and condition of “fair.” Two of its voices are out: VCAs 2 and 4. Meaning the synth works in all ways but skips those voices when playing in poly mode. Unison mode sounds great, of course. But anyway you probably know the drill with these 106 voice chips. You can give the chips a bath in acetone and hope for the best or replace at ~$50 each. Replacement of all the chips at once seems to be the more convenient option, you usually get a discount for buying all six, and it is a permanent solution. I like doubleheart audio because they'll do the work for you and calibrate as well when you send them the motherboard. Estimated cost of chip replacement is $250 DIY to 300+ for full service."
