Vintage RS Slider (100k Value) Question
Posted: Fri Sep 26, 2014 4:02 am
Hey,
Someone is offering me an old (NOS) RS slider/potentiometer (just like the ones that were used on the original Marshalls). Now, I know that the bias trimmers for the 12,000 build is somewhere in the 20K-25K ballpark, yet I saw a schematic that George posted a while back of an amp that was only a few serial numbers away from the EVH holy grail amp and the value for the trimmer was 100k.
My question… Is it not worth it to bother with a part with a value like this (100K) for my 12,000? Also, if I do use the 100K, are there any ways for compensating for it with maybe a change in one of the resistor values, etc? I really need help here, especially since I don't know what was generally used in the Plexis of yesteryear. I appreciate any help.
