Mesa DC-3 need help!

Post by 45auto » Fri Mar 10, 2023 10:18 pm

Got a Mesa Boogie DC-3, think the 240 eq band is inoperative, maybe inductor? More concerning is with one channel set to clean and other distorted, there seems to be "bleed over" distortion into the clean channel? Thought at first speaker might be damaged but when I reduce distortion on distorted channel it goes away on the clean channel. Does that make sense? Anyone seen anything like that? Thanks old and new friends

Got a chance to fire it up again. The lead channel bleeding over into the clean channel only occurs when foot switch is used. Does not happen with footswitch unplugged and channels are switched with the front panel switch

Well I'm answering myself I'm hoping. I was using a Mesa triple rectifier footswitch thinking it was like any of the old footswitches. Apparently Mesa does have different footswitches for different models. Maybe even different years of make. Going to order DC-3 style "A" footswitch or equivalent. Maybe this solves the bleed over issue. And when Boogie parts store re-opens in April will purchase the .39h inductor for the 240hz band on the eq.
