Using a RC-3 for about a week - 2 gigs and it worked fine, purchased off eBay. Last night the signal was very weak when engaged, and this morning there was no signal at all. When its 'on,' no signal is passing through. When bypassed its fine (true bypass). I've tried a new battery and a 18V power supply on my board specifically for it. Any items to check before I try to get a replacement from Barge Concepts? I know its not a popular comp, but its just a Ross clone, so maybe someone has some insight?
