Working on a 60B cathedral. Im stuck on the wiring for the tone control. Seems these Philco controls always get me messed up.
http://www.nostalgiaair.org/PagesByModel...013793.pdf

Its a 30-4008 two position with a .01mF always connected and a .015mF switched.

Does one lead of each cap tie together and go out to the output tube, and the other end of the .01 connect to the tone control housing, and the other end of the .015 connect to the lug on the switch lever??

Yup Looks like it. If you like you can play with the values of those caps (making them smaller in capacitance) to increase the high frequency response of the audio amplifier.
