Here's a question for anyone who has or had a model 15. Does the tone control do much when switched in? My 15 is a little unique, maybe. As far as I can make out the tone control and the tone control circuit on this radio is from a model 19 code 128. It has an extra bakelite block with the caps for bass that go to the 2nd audio tube 37 and the input trans.

It works but very slightly changes the tone. I clipped in some more capacitance on the caps inside the tone control and got hardly any change in tone. I'm just wondering if the original tone control and circuit made a bigger difference in tone.
Thanks for any input.

Dick
