Title: Crate GX-40C problems
Post by: Blooze on April 12, 2009, 11:52:45 PM
First of all, thanks for providing this forum.  I'm hoping it'll help me troubleshoot this old DSP amp of mine I haven't used in a couple years.

Tha last time I used the amp it was wanting to fade in and out after it warmed up for 10 minutes or so.  I fired it up this weekend and after 15 minutes it seems to work now, but the chorus function is gone, so I wonder if it was the chorus function going south and affecting the volume somehow? 

Does anyone have a schematic for this old Crate model?  At least that would give me a starting point.  Any suggestions of where to start looking would be great.  I've built several hi-fi tube amps, so I'm not shy about digging into the amp.
