Hi all, Have some conflicting info on the cap values for this tone control. Both my Philco schematics(one early and one later production) list .01 and .02. I have Ray's original "Philco Condensers and More" ( Great resource book!!!) which lists a .02 and a .003 for this tone control. The Philco Repair Bench does not list this tone control. Does anyone know which would be the correct ones? I'm assuming the .02 value is correct. Thanks-Ken

Those caps aren't that critical, either combination will work. Use what you have, just follow correct layout (placement). Yes, the Philco Condensers and More book is nice to have!! Best of luck with your restoration.

Go with to .003 and .02. That will give you a fair amount of difference between the two setting.

Yes, agree with Terry, .003 and .02 are a good combination for steps in tone.
