I’m working on replacing the caps on this 650 and the tone control has me confused. I know there are 2 - .01 caps and one 3000 mmf cap to go in there but I’m not sure how to wire them in properly. There are 4 wires coming out of the tone control, 3 of them are connected individually to the three lugs shown with the blue arrows on the photo. The 4th one is the red wire that leads to backelite block #63.

If someone in the Phorum could assist me as the where the connections for my replacement caps should go it would be appreciated.

I’m new and still learning this hobby and not real fluent in reading schematics. Thanks.
