The resonance potentiometer sends out a voltage, which controls the
internal resonance circuit in the 2044 via VR3.
But this voltage controls also the first VCA (double transistro Q10
after the VCF). This is, why the output level increases.

The question now is: does the resonance control voltage reach pin 2 of
the 2044. If no then check the voltages at VR3 and R2. I could imagine a
cold solder joint.
If the cv reaches the pin2 of the 2044, then the resonance VCA in the
2044 is dead. Then you have to replace the 2044.
