model 42-322 audio distortion
#4

Well guys, I found the trouble. It is one of my most embarrassing moments. For someone with my experience and qualifications in electronics I should be tarred and feathered.

I had added a single terminal of a terminal strip just to have a place for the ICL (inrush current limiter) and used a very strong glue called shoe goo to hold it to the chassis. I failed to notice that the rivit in the back was touching the chassis. I HAD TO HOT LEAD OF THE AC GROUNDED TO THE CHASSIS. What a dumb mistake!

With it now ungrounded the radio plays BEAUTIFUL and really pulls in the stations with remarkable clarity. NOW the project is done.

Thanks to all for the support. This was a very interesting project. My first excursion into the relics of the early 40's.
Best Regards,
Dick KF4NS
