“The external physical condition can be seen in the attached photos. There are no cracks or loose joints in the case and the instrument is very sturdy. Oscillators 1, 2, and 3 bleed through the headphone output. There is a constant background drone. This does not come through the main output and does not affect performing or recording. After warming up and being played for an hour or so most of the keys are stable. Some of the upper octave keys will go unstable and the frequency will fluctuate from time to time. Most switches and pots are scratchy when flipped/turned. Sometimes the main output switch does not work. If you turn if off and then slowly turn it back on it will work. I worked with the instrument for 3 hours yesterday and set all the internal pots from the rear panel and those are the only problem notes I have. There is a somewhat loud key-click, but that is not heard in the output, and would not be heard during a performance or a recording session. Also there is one yellowed key. That was a replacement key from the 70’s that yellowed over time. (According to the roadies they did not know what happened.) The thing sounds absolutely awesome and playing it brings back memories of past gigs and of hearing Keith Emerson or Rick Wakeman back in the 70’s.
Included with the instrument is a copy of the users manual and field service manual. Also included is the original sound settings guide (with some pages missing) and the S-trigger that is used to provide an external input to the filter banks. The sound guide shows oscillator and filter settings used by Keith Emerson and Rick Wakeman on a couple of their recordings. ” Click here to search for synths on eBay
