Philco 70 speaker
#6

I.     Thanks for diagram. It helped. Next issue- I now have a steady hum. Tone control changes tone of hum, volume control does nothing. I noticed that the two electrolytics were in place- first one still hooked up- 2nd one was a 20 uf instead of 6uf. I replaced the first with a 10 and the second with a 22. I included photo of speaker wiring- hopefully got it right. Good magnetic pull on speaker.
