Analogue systems

Hello everyone,

I've just started my modular project with a minisytem and am having a few problems - i think their may be a fault with this old system i bought second-hand. Initially the EG depth pot was very noisy and tempramental but the system overall worked. Now i can only get the very tiniest signal from it, even when just testing by sending an osc straight to the VCA and turning up the signal and initial level - its really really quiet - if i played another synth with my monitors that loud i would loose roof tiles! Seems like somethings broken in the VCA now as well as a bad EG depth pot - any thoughts before i send i bother Bob with this and send it off for repair?

Cockpit trouble is always a possibility of course, but i think the basic test shows somethings up?

thanks, Dan
