Sorry - please disregard this for the moment being.
I think I found the error, and ordered some new caps with correct specs that I will try before pestering you folks again
Original message on pause:
I know compressors can be noisy, but I think the hiss form my Boss CS-3 is a bit more than usual.
It's quiet when used only as a limiter (below 12 o'clock), but there is a lot of hiss when using it as a sustainer (past 12 o'clock).
I hoped that modding it would help, but it seems to have gotten worse.
I probably screwed up when installing the Monte Allum Opto kit.
I noticed more hiss after replacing C10, and have since tried with another cap in that place with no luck.
Not a big problem for me actually, since I rarely use it past 12 o'clock. But it annoys me, because I want it to work properly.
The question is how can I test this circuit?
Any suggestion to troubleshooting or solutions are welcome.
