Well, I took reconnected C7 to the plate. I had to wait until my wife was out of the house to try it out because the volume is quite loud without the 1 Meg pot. Indeed, the plate voltage increased about 40 volts, from 175v to 215v. I rigged the set to switch back and forth with the same loudness, tried various stations, and listed with and without hearing aids. And I can't tell the difference. Furthermore, I don't have a critical ear, so it doesn't sound that bad to me.
I considered the possibility of the speaker magnet rubbing, and I know how to check that out. I've recentered a cone successfully before, but I'd be hesitant to put that effort into this set.
I was getting ready to put in a line filter/safety cap. After that it will interesting to try dieseljeep's suggestion.
Thanks, All
Henry
