plugged guitar  in it , the compressor led lits up when i play no sound at any out put.
what could be the problem, put  2 JJ 12ax7 in to it  and  they warm up, after some time hot.
if it tip on print behind 2 pot meters  it hear little noise on outputs.

MarshallJMP:
Well from the pic you send me you seem to be missing U606 which is a NE5532 opamp.

Damn-Danny:
First the MP 1 got modded, the MP2 can wait, first collect the needed IC's.
And hopefully it will work.
Maybe the LCD don't need to replaced.
Hope Marshall JPM can help me out then.
Tomorrow i will send the MP1 to him.

Damn-Danny:
Hope I'll find all the missing IC's. one day

Dante:
No worries, Danny! MJMP will get it working again or at least have an assessment for you to consider. You're in good hands :thumb-up:
