Re: Suddenly out of tune -but still problems after changing PC-1 and R93

2008-08-21 by hjulskov

Here are my measurements:

5: -9.90v
6: -9.92v
7: -8.55v

Also I discovred an interresting thing -voice 3 + 5 are slightly
distorted -sounds like mg (running at a high frequency) is applied,
but frequency does not change when changing MG, PWM or effect
frequency. Also when probing pin 6 on IC17 all voices are distorted in
a similar way.
