troubleshooting an MXR Stereo Chorus

[Nicholas Pelkey]

Hey gang,
I just got back from my local guitar/amp/effect shop where I was checking on the progress of repair on my old MXR Stereo Chorus.  Unfortunately he didn't dare touch it saying it was "digital" and that I should send it to MXR.  Well anybody who may have tried for service on MXR products must already now that the MXR line is run by Dunlop and that they only service the new stuff.  I was hoping this guy would at least run a few tests and point out the part that crapped out and I could take it from there.  I thought it was a loose op amp at first...then I resoldered that.  The problem was that the signal would cut out and make lots of noise.....now it just makes lots of noise.  I can sort of hear the effect in the background lending me to believe that it might just be an ic or something.  I know there are loads of stomp-box experts out there so any leads would be great.  If its any consolation I plan on using this with my synth (all analogue) rig.
Thanks in advance
Nick P
