Micromoog problem/ where to find parts?

Hello,

I have a micromoog that is experiencing a problem with the keyboard.. basically if a note is played it sort of makes a weird warbling sound then sometimes gets to the note played or sometimes is sort of flat.. I tried cleaning the contacts and it hasnt seemed to make a difference.. the weirdest part is sometimes it will work completely fine but then it eventually goes back to the note warbling. here is a sound file so you can hear..

I’ve tried controlling the moog through the cv/gate inputs and it seems to be fine, no warbling issue.. so I think it may have to do with C212 or Q201… which leads me to an additional question.. C212 is a polycarbonate, 0.27uF, 50v, 20% tolerance cap.. Im assuming these arent in production anymore because I cant find anything on mouser, digikey etc. SO does anyone know of a source for this part OR if there is a cap that is in production that would act as a stand in?
Same question for Q201.. its a dual FET E402, which also seems to not be around anymore.. any ideas for subs?

THANKS!
Ian
