my continuing saga with my DC3.. broke the master volume pot on the lead channel last night.. during breakdown at a gig, I must have knocked it against something. I recovered the knob with half the pot shaft still in it. as a temporary measure I could probably carve a slot in the shaft left in the amp and use a screwdriver to adjust the settings, but that's downright ghetto. My nearest Boogie dealer is in 70 miles away in tucson. The last time I took my amp there, they told me it passed the "bench test" and did nothing. I still had the same problem. It turned out to be a blown speaker... I'm the idiot for not figuring that out, but a good tech could have made that rocket scientist discovery quickly. Question is.. how hard is it to replace one of these pots? I'm told that the pots are attached to a PC board. ? Is it best to take it to a authorized tech or try it yourself... any other threads on pot replacment? thanks....
