For those mad enough to attempt a repair or god-forbid restoration of their PolyMoog, here is a running list of parts I have/will/need to replace. This will be updated as I get stuff.
Power Supply has had its capacitors replaced. Note the 4700uF is a radial -they were out of axial capacitors in the rating I needed.
P o w e r s u p p l y : : : : : .
3x 470uF x 35V axial capacitors
2x 1000uF x 35V axial capacitors
1x 4700uF x 16V axial capacitor
3x LM723CN chips (not sure if these need replacing, but they are 33 years old and replacements are $0.65 each.)
Few synthesizers have such a bi-polar reputation. Amazing sounding and tedious to maintain, much less restore are the two poles of this equation. Moog churned out a few of these – I am guessing a little over 4000 since this fellow is serial number 4021 and I’ve never found a reference to a later one. Gary Numan famously used the Polymoog and so did a list of other luminaries if VSE is correct, but there isn’t anyone recent on that list. I’m excited to fix this to see what it can do in a modern setting.
It just happens sometimes. You mention you have an X you are looking to get rid of, and a friend says they have a Y they’d like to get rid of. A little cash one way or the other sweetens the deal. In such a way this complete, clean, low mileage, semi-functional Polymoog joined the menagerie.
