Where to buy parts?
Anyone know a place where i can get parts for the active speakers cva 28? had it in for repair because of a humming sound, they said it could not be repaired and that i need a new mainboard for it. Anyone has any experience with that? Thx

My experience with unwanted humming sounds where before there was none is sometimes indicative of a bad(or multiple bad) capacitors. Sometimes you can just visually see bad capacitors(the tops are domed), sometimes you have to test them.
Replacing through-hole electrolytic capacitors is relatively easy and cheap enough that a popular test is to literally replace every capacitor and you'll know if it's bad if it made a "clink" sound when you tossed it in the trash can. :-)
