I have a piece of equipment that has a dial cord. The cord is wrapped twice around a 1/4 in diameter brass rod which is the shaft for the knob on the front panel.
In one position the dial cord slips leading me to turn the knob more until the resistance is overcome and the main control starts to move again.
I really don't want to have to disassemble the thing and replace the dial cord. I don't think there's any grease on the shaft or the cord (but the cord is slightly discoloured).
Are there any tricks I can employ to resolve this? I've though of spraying the area with isopropyl alcohol to remove any stray grease, but I don't know if there's any issue this might cause with the cord.
Any advice?
I read this. Isopropyl has been used by people, and violin rosin may also be a good idea (and weirdly enough, I have some of that).
I have another issue to fix. The instrument was delivered knob side sown from a height :-( In the image below you can see a pot that has been pushed apart.
And how one of those knobs survived (or didn't)
