"This Prophet T8 analog synthesizer (Serial 1008-000742, 3.8 Main ROM, 3.7 LS and MS ROM) works but needs some care and repair. It has the following issues that we can detect:

1) Unit has been stored in an Anvil metal case for around 8 years. The case foam decayed, leaving a sticky residue on the unit. We have cleaned the exterior as best we can, but there is still some slight staining of metal and wooden surfaces and some foam has gotten inside the unit. The black paint or enamel on some of the knobs appears to be loosening. There are some minor scratches on the top lid, and chipped paint on one edge of the lid. The F and G keys in the highest octave have odd spacing, the G key rides a bit high and highest C a bit low but this does not appear to affect play.

2) The Anvil case is solid and sturdy on the outside and has average wear. Inside, its protective foam has deteriorated into sticky powder and has been removed. New foam can be easily purchased and glued in to refurbish the case. The synthesizer will be secured in temporary packaging inside this case for shipment.

3) The T8 has 8 voices. In Split mode, 4 voices are assigned to the right side of the keyboard and the other 4 are assigned to the left. (The point between right and left can be adjusted to any key you choose.) In Single mode, all 8 voices play the sound of your choice (right or left), and in Double mode, a pair of voices (one from the right and one from the left) plays each note, for a total of 4 pairs.

On this particular T8, all 4 voices on the right appear to work properly. 3 of the voices on the left have some problems. (One of those is different in a minor way). It's probably just one component in each voice that needs to be replaced. Without replacing them, those voices play sounds, but not the same sound as is desired (one is close but not exactly correct; the other two seem very different). It is possible to disable a voice easily, just hold down a key that's playing the bad sound, and at the same time hold down RECORD (the red button) and press 7. After that, the disabled voice will not play until the unit is turned off and on again, the processor will just choose a different voice to use instead.)

4) The factory presets have been overwritten. If you get a cassette of the digital data for the presets, you can load them back into the T8 through a cassette port. Or you can save your own presets, of course."
