Psikyo SH-2 volume pot replacement?

kyletwentytwo · Mar 29, 2026

Hi all,

Anyone know if it is possible to source volume pots for the Psikyo SH2 PS3/PS5 boards? I've got one giving me occasional scratchy/poppy audio even after a recap, and I'd like to try a new pot to see if that could be the problem. I also replaced the 4741 op-amp as it had gone bad. Any other ideas are welcome, too.

Did you try to put contact spray in the pot ?

Is this the same problem as discussed here? https://www.arcade-projects.com/threads/gunbird-2-audio-improvement-wip-help-wanted.13212/page-6

Not quite, I get full volume, just lots of crackling in the music. But strangely it isn't always present, maybe half the time. But when it crackles it is very noticeable.

I always do that, sometimes it's just dust in the pot, you put in the pot and you try up and down the pot (power off). And then you try power on.
