Problem with Mesa/Boogie DC-3

[Mitchishin13]

Hey all, I just bought a Mesa DC-3 about a month ago in mint condition, she's been working great but just the other day something went wrong with the footswitch. When I plug the footswitch in the lights are powered and functioning correctly but no sound comes out of the amp. If I unplug the footswitch I get my lead channel only. Has anyone experienced this problem before? Is there any way to fix it or do I need to buy a new footswitch all together?

Can you post the schematic?

I don't have the schematic, however it would be useful, might you know where I can get a copy of it?

That will definitely be useful if I have to go in there and troubleshoot, thanks! where did you find that? I've been looking for a schematic for my friend's express 5:50 as well

I found it at Scribd and had to feed it a pdf before I could download it!

There is also the "schematic request" forum here!

Bote some DC-3's use the Studio Caliber Schematic for the EQ & negative 30 volt supply
