I am trying to implement the change for the tone control.
Since I do not know what the new one #30-4069 looks like I need to mod mine which is a 6-tap, not sure if it is the 30-4033 shown in the sch..

I am not sure it has same number of taps as the new one (it mentions 4) or is it the same?

They have 7653-C backelite cap for 0.025uF externals but seems like both caps are connected to GND, so not sure I can use it the way it is as only one 0.025uF cap is grounded.

If someone has a good account on moddind the whole thing I'd be grateful.


Found this in Google archives.

This however does not show what the description in Production run #4 says it should be.


Aha. Found this

Seems to be it.

So the link before shows diagram wrong, and then the backelite cap should have the two caps in series conbecting together at centerlug.
