Hi, hope some experts out there could help.
I have a guitar which its volume and tone knobs need to be replaced.
I couldn't find the parts with the exact values marked on the existing once. the marking is like the following:
M250KΩA
33K
Question 1: what are the definations of the marking? eg.whats the "M" stands for?
Question 2: what is the bottom value (33K) for? as all electronic stores I visited don't have the one like that, and no one could answer what that value is.
Question 3: is it very important to get the exact value one, or it doesn't really matter?
Thank you
