Cannibalizing filter caps from a C64

Hi all, I was wondering if would be possible to use the capacitors from the same C64 board where I took the SID, and if somebody already tried to do so.

(this question arose because it looks like the filter on my mbsid isn’t working… and I didn’t find those “Styroflex” caps, only ceramic ones)

I don’t have a board here so I can’t tell by myself…

Many thanks!

You could desolder the original-caps, but they are ceramics too. I wouldnt do that for myself as new ceramic-caps are very cheap here.

I would not use any unsoldered capacitors from the C64 board because of the aging process they all undergo. It’s especially an issue with electrolytic capacitors.

Not to mention…the filter should work (although not as well) with ceramic caps… so if it just doesn’t work, it’s probably a dead SID :frowning:

Thank you for all the answers. I didn’t know the original C64 caps are ceramic too, I thought they were Styroflex as specified in the components orderlist. I just read about Styroflex, they “simply” have a better tolerance and quality.

Fortunately, when i wrote “it looks like the filter on my mbsid isn’t working” I was wrong… for some reasons I didn’t update the patch parameters in JSynthlib, now I enjoy using the step A surface  :stuck_out_tongue:
