Going through a fleece bay parts kit for a Pioneer RG-1 and I'm finding some questions.

Can anyone tell me if I can use this cap?
It appears to me to be a 1uf 63v film cap (not sure what M stands for). The parts list calls for an electrolytic.
What raises the question is that the schematic shows electrolytics both polarized and non-polarized in the signal path.
I believe I've identified C1 and C5 by process of elimination. They were supplied as Wima film caps.
C43 is electrolytic, has no indication of polarity...non-polarized?
Left channel illustrated, right channel similar. BTW, kit came with no parts list, no instructions. Joe spoiled me I think...

M is the tolerance grade, M=±20%. This is part of the datasheet for the cap easily found on Mouser or Digikey or from Wima.
You can replace polar caps with non-polar caps.
Yes C43 is a non-polar cap.

Buy your kits from peace.love.music / affinity for artifacts, a regular ak member that puts together quality kits and sells on the bay. Not someone that just stuffs bags with parts.
