I am also having the same issue but with my C#/Db key. I can measure the resistor and it read accurate however it doesn’t work not matter where I touch the PCB or other keys and resistors. I do not have any 750k resistors around, but do have some 680k. However I am afraid of separating the contact to the lead in the board as I have already reflowed the solder then pulled the resistor out and re-installed. Will putting in a 680k affect the tone of the C#/Db key?
