Congratulations. Another fine old radio saved from being trashed. Good work!
Yeah, I played around with the field coil and noticed that it was a little loose and shimmed it with a couple of business cards. That took care of some of the noise. But it really seemed like the bass was distorting anytime I turned up the volume or increased the bass control. So I decided to try different impedance on the Output transformer and that seemed to solve my problem. Depending on the program material playing I still get some distorted bass on the high bass setting. However I think this is because I used .1uf capacitors to replace the .08uf that were in the tone control. Plus even AM stations seem to turn up the bass a lot anymore. I was worry about low bass response because the 125E is only rated 150Hz - 15kHz but it seems fine. I imagine when I get it back in the cabinet I will hardly ever use the increase bass controls.
