Pics of the inside below.

"This is fully serviced. All power supply large filter caps replaced, the ground connection from the molex a known failure mode has been tied permanently.

For H910 mode hit the 'algo' button and it will remove the 'deglitch'.

Memory chips, brand new, changed to ones that only run on 5v rail and not three different rails, they run much cooler, also when something goes wrong they don't get cooked. The early DRAMS used by eventide, those that were available were failure prone - the Personal Computer revolution quickly led to better DRAMS - which are deployed in this unit.

Electrolytic caps, tested, replaced for low ESR - top quality the best available

Better quality ceramic capacitors around DRAMS to drop noise floor to the lowest possible. They are mil-spec about £3.50 each for a tiny component and there are 10 of them.

Ripple checked for lowest noise performance possible

Tantalum where there should be tantalum - again the best.

Heatsink compound applied

A lot of the character of this unit comes from two factors; one the early digital use of memory chips to store the audio delay line with ultra fast bit slicing AMD bipolar processing chips and two the DBX companding (x3) - these really resolve the noise associated with early digital and improve signal to noise."

"Fully polyphonic 48 key analog string synth. Classic 70's string/ensemble synth sounds. Amazingly thick, and warm sounding- sounds huge and dreamy. Used by Jean-Michel Jarre, Tangerine Dream, Vangelis, Hawkwind.

Works great. Voice selection buttons/switch contacts recently cleaned, and working well. Built in case has new latches installed.

Treble eq control is very scratchy, but works once set. Some of the other pots may be slightly scratchy, but all work. Light on power button does not light up- power switch is functional- unit powers on/off, but light doesn't work. Scratches/nicks on top (top is great for stacking other gear on).

I've had the pleasure of owning this beast for 20 years- it's gotten a good amount of use, but has been well taken care of, and rarely taken out of the house.

Stacks 3 oscillators per key/voice in octaves- you can also turn two of the oscillators on or off to use two or one oscillator per key/voice. Can also detune two of the oscillators separately to create a thicker, layered sound. Buttons/switches for selecting sounds can be simultaneously pressed to stack sounds. Built in phazer sounds excellent."
