Today I started rebuilding the tone control, and I noticed that there are two wires that came to the middle tone ctl position, not one.
I separated them, and then I realized that there was a capacitor between the 1st and the middle positions, but there were no cap between the 1st and the common at all. So the capacitance of the 1st position is the series value of the capacitor between the common and the middle and the one from the middle to the 1st.
Ok, one cap less.
Here it is:
It is very much the same as 30-4043/4208/4220/4378/4056 parts. The values are close, theirs are 10nF/15nF/10nf wheres mine are 22nF/15nF/15nF. I wonder if I should just take the values from the book.

People who do not drink, do not smoke, do not eat red meat will one day feel really stupid lying there and dying from nothing.
