Moog Prodigy all Capacitors replaced with resistors?!

[retrobish15]

Hello I was hoping someone could help me. I just bought this Moog Prodigy (as is not working) and everything worked except oscillator 1 (i.e filter, contour. glide... everything! every note!) but when I turned up osc 1, nothing. sounded great too just with one osc. I am a hobbyist electronics person (very low level but i did build my own monophonic synth from scratch) and I thought I could try and fix it. when opening it up and looking at the schematic I noticed (which may be surprising to you) but it seems like ALL the tubular capacitors have been replaced with resistors. That cant be right!? As you can see in the images, C18 is a resistors? The serial # looks to be 10304 and the model number is 366A. it looks clean on the soldering underneath. I am shocked 80% of it works. Any help would be much appreciated. https://imgur.com/a/JvUzLQB

Appearances can be deceiving. Axial capacitors have been manufactured in a similar package to resistors, you'd need to measure to be sure - but my guess is that this is a red herring and your troubles exist elsewhere in circuit.

Happy hunting!

Your components look fine to me, same capacitors as mine - definitely not a problem.
As crochambeau said, your problems are elsewhere.

Yeah the ones in the light green packages are capacitors not unusual to see this for stuff of this era but definitely confusing for newbies. Common reason for one oscillator not to work is the transistor array chip which is the heart of the oscillator, have a look at schematic it would be a CA3046 or 3086. They can still be found and quite likely to be in a socket so easy to remove.
