Hi All
Tone control part # 03137 for a model 112 with push-pull 47s. Does anyone know the cap values? Philco repair bench doesn't list it.
The earlier tone control with push-pull 45s is a different part # so maybe the cap values are different.

Thanks
John

The "Philco Condensers and More" book by Ray Bintliff (may he RIP) comes in handy again. He shows the first cap to be a .015, and second two being .01 mfd. It seems to work well on my 112X.

refeenstra answered the question but just as a reminder to folks...

many of the earlier Philco schematics are nicely annotated by Ron and can be found in the Library
Cheers,
Bob

Thanks guys. It's funny that two different part numbers use the same cap values.
