The cap checks good, Mike. Voice coil ground is ok.
Now, for the good news. There's a 1k resistor that goes from the low terminal of the volume control to ground. The 1k resistor was right on. I jumped it with another resistor and the hum went away. After some experimenting I settled on a 470 ohm resistor to replace the 1k. I'm sure someone can tell me why it works, but it sounds great now!
Thanks everyone for your input. I hope you all had a good Christmas and looking forward to a healthy and happy new year.
