Hi gang!

I have a RS-120 comb filter that <I think> I plugged the wrong way into my Zeus power supply. Hence it not working.

I would like to repair it, does anyone know which components might have broke? The resistors and caps look fine to me. I'm guessing one of the four IC's gave out?

Maybe someone has schematics or know-how if these IC's might be prone to a power surge. They are as follows...

1X -16 pin HCF4046BE - W993A9701 -MALASIA
1X -8 pin MN3207 - M 46
2X -8 pin RC4558N - C8336

If not, I'll dig deeper and check out mouser, but wanted to check in here real quick.

thank you!!!

Was it working before you plugged it in? RS-120 needs 5v so would appear dead anyway in a normal non 5v system.
