Title: DC30 build issue....... Post by: telemad on July 20, 2009, 03:59:25 AM Got amp started up and channel 1 is sounding good but channel 2 is having issues..... The channel only gets sound if volume knob is turned to zero.. any other movement I get scratchy and pronounced hum and no sound from guitar.... Checked wiring against layout and it looks right ...... bad pot??? Kind of at a loss here and trying to avoid $50 per hr bench time......

Post by: Mitch on July 20, 2009, 08:24:12 AM Obviously double double check your soldering- easy to get a 'dry' joint somewhere- check the EF86 is OK & one issue I had with the DC30 was the insert jacks for efx send/returns weren't making a good contact- I solved this by cleaning the jack make/break contacts with mild abrasive & switch cleaner and re-tensioning the contacts slightly- you can check continuity easily across the send/returns with a multimeter...
