Philco 20 Restoration
#24

Steve, since you are not adverse to applying modifications I thought you might find these two articles I found interesting.  Popular Science has all of their issues online to read.  In the July 1933 issue, pages 51-53, there are two articles I found curious.  One was a simple way to add a tone control to a radio (model 20?), and the other was modifications to use more advanced output tubes.  The only concern I had was if the tube conversions would overtax the capability of the power transformer.  If nothing else, interesting reading.  Take care, Gary.
