"This Synthesizer is in great working condition and has recently received a lot of attention. It has been meticulously cleaned inside and out. All the pots and switches have been cleaned with Deoxit for trouble free operation. ALL the tactile switches have been replaced. You will have no problem with pressing hard or double pushing to make the synth. respond. The keyboard has been disassembled and all PCB contacts and carbon pads cleaned. No key issues to worry about.On the processor PCB the battery has been replaced with a lithium cell so no more chance of damage from the original Nicad battery. Some random memory problems have been fixed that were tracked to aged 4000 series Cmos devices, a typical failure point with this vintage synth. All is well now with no memory issues.
The six LEDs on the voice PCB have been replaced. These are not normally visible but make it much easier to see than the original dim ones when you are debugging or Mod’ing. PC-1 was also replaced as this is a typical failure point. The long and tedious adjustment procedure has been performed so it will play and sound as good as the day it was born."
