"Cosmetically- It has a new Koa cabinet which looks stunning. Google Koa and see what comes up. The black bottom cover has also been restored. It has a new set of keys, almost all external screws have been replaced with new ones, it has a new set of knobs (from the original company that supplied them early on), the back metal back panel has been re-anodized and it has new Switchcraft washers & nuts.
Internally- Apart from any repairs, it has been disassembled and cleaned, all electrolytic capacitors replaced, all switches and potentiometers cleaned, has the "switch mod" for better reliability, all trimmers on the oscillator card replaced, the edge connectors resoldered, new 1% resistors and it's been fully calibrated. The keyboard has been disassembled, cleaned, key contacts cleaned, all parts inside have been relubed, it has new key bushings (action feels great) and the keyboard, pitch/modulation cinch connectors have been replaced with better molex connectors. This one does have the "buffer board" for better tuning."
Update: pulled the auction link. This one appears to be a scam.
