Yamaha CS-60

via this listing

"Completely restored - as new.

This is not just another CS 60.

She is fully recapped, about 300 caps were replaced. Not only the elco's, but also most of the ceramic caps were replaced.

All logical IC's were replaced.

The power supply was recapped, calibrated, the works.

I swapped the original power cord with a hi-end power cable. The original one was of poor quality. The new cable is longer than the original, with larger diameter conducters, and better quality copper.

The power cord features a premium CEE7/7 Schuko plug which fits most EU outlets. In case your region of the world has a different power plug standard, it is easy to swap this plug with one that fits for your type of power outlet.

The original (low quality) audio connectors from 1976 were replaced with modern Neutrik gold-plated 1/4" jack connectors. Gold plated contacts protect against oxidation and corrosion.

I carefully added an LED on every voice board. These light up when the individual voices are in use. For tuning this is indispensable. You can see the LED's in action in the video I refer to at the end of this add - starting from 16m28s.

Just about all of the metal work was professionally sandblasted, treated against rust, chrome plated, polished, and/or powder coated.

The instrument was cleaned inside and out.

All faders and potmeters were cleaned and lubricated.

The S+H board was thoroughly cleaned and rebuilt - see photo. The instrument detunes far less over time thanks to this.

All of its original Yamaha type IG and YM chips are installed, as it came new from the factory.

Original cover + chrome music stand are both included.

Two of the fader/levers are missing on the photo's in my garden. Those have been remounted in the meantime. I took the photo's when the instrument was nearly finished and the light outside was perfect for a photoshoot.

I published a couple of video's on Youtube with this very synth - look for:

Yamaha CS 60 - She is Alive

Published on Jul 31, 2019 Metralon

The playlist above starts with a demo with the description directly below, followed by a number of restoration videos.

"SKIP to 1:49 if the LFO detuning at the beginning of this video is too much.

Very first improvisation after one year of restoration work.

Ok that was a lie: it was my third improv. The first one was utterly magical and was not recorded; at one time the synth spoke to me, I swear! That was a couple of days ago. The second improv happened yesterday and wasn't all that great. So you'll have to do with this third one as a first encounter. In the notes of John Williams: d4-e4-c4-c3-g3.

With due apologies for the length and randomness of the improv; the CS60 universe envelops you and before you know it you're 40 minutes in.
