btw,
Is there someone kind enough to take a pic of the backside of the board of the area of the RAM chips? I could pinpoint vMEM measuring points if a pic was available. I'm afraid no.
Such a high value VR would have way too big change of resistance per degree of rotation of the dial.
edit: Meaning dangerously steep, sudden increase of voltage after a certain amount of rotations. 1kΩ VR is OK.
