This p5 stays in tune all the way up the keyboard and all functions work 100% and sounds just as it should! It was just played by a tech and given a very clean bill of health before putting up for sale.
Here is a complete list of work done to the synth:
Power supply: replaced cord, bypass caps; rewired for 2716 ROMs
Front panel: replaced pot, 3 dead LEDs, bypass caps; cleaned pots & switches.
CPU board: replaced battery, bypass caps, U337 DAC reference, ROMs.
Voice board: replaced caps, LM311 tune comparator, LM348 quad opamp, one SSM2020 VCA, two SSM2040 VCF chips.
Replaced rear panel 1/4 jacks. Replaced fuse holder. Replace Rear P5 Sticker with nos original.
This synth is a very nice example of a fully functioning REV 2 Prophet 5."
