Koma BD101

Hello Komanauts,

Hope someone can help me with a BD101 analog/gate pedal.
one or more the opp-amps seems to be broken, but thera are 4 of it.

symptome: Gate and Delay are working, but at very low level. As soon as I give more gain with the gain-slider it become even weaker to zero. 

Does anyone have a circuit diagram or measuring advise familiar with this problem?  So I can figure where to find.

Any idease are welcome to let this sound schredder schream again.
