Moog MG-1 Realistic

This MG-1 had some serious issues, nothing was heard from tone source 1 or 2 and the bell source. Some tones of the polyphonic section where either dead or played the same octave over the entire keyboard. All of this was fixed, Tone source 1,2 and bell was fixed by replacing the 741 OPamp in the Keyboard CV generating circuit. The Poly section fault got fixed replacing the divider IC's with new ones. This MG-1 was also upgraded with new caps and cosmetically enhanced with new graphics for the front panel. It was also rebuilt for 220Volts.

Might seem to be ok looking at it from this point of view.

Big scratches

More scratches.

Some of these dividers had gone bad and some poly tones sounded the same some didn't sound at all.

The MG-1 came as 110Volt standard. Now rebuilt for 220Volts.

Old sliders, this whole PCB smelled like someone had kept the MG-1 in a smoky bar

No it is not what you think it is ....
