MPC 2500 - right output channel issue

Hi,

Now I've got right main output channel not working - it does not produce any sound (on a headphones and on a channel itself). I know, that general solution is to reroute MPC to not to use main stereo out, but in this case FX are not working and I want to use compressor on a live gigs.

Can somebody suggest what goes wrong?

Thanks!

Ok.
It turns out, that Master Volume knob resistor was broken. Temporary replaced by Record Gain knob (connectors were switched).
