Doepfer

I seem to have an issue with the tuning on one of my A110 VCOs.

Normally when i'm going to play i let my modular warm up for about 20 or 30 mins and then tune the oscs, and they stay in tune fine, but one of the VCOs had it's in tune point right at the top end of the tuning pot. Now that seems to have shifted a little so i cannot tune that osc as the knob doesn't go any further right, and doesn't have enough range for me to switch to an octave up and tune it down either.

Is there an easy fix for this without the module needing to go back to mr doepfer? Like a tuning trimpot on the board or something, or a resistor i can swap out?

the adjustment procedure can be found here

scroll down a bit to find it (in english), i would recommend reading all of
the adjsutment section before doing it :)
