Antenna connections for 38-7
#4

Not sure about how to connect the antenna and ground, I did a voltage check. I found that I have what I believe to be a ground loop. I measured about 46 VAC from any antenna connection (Red, Black and Ground) to the outlet cover screw. That I am sure isn't right. Where would this 46 VAC be coming from? The radio does work, on both BC and SW but I am not too happy measuring 46VAC from chassis and the antenna connections to ground.

Help!

Now then there may be a phantom voltages from a modern digital meter appearing because of the capacitors connected to the incoming power line (#47 on diagram.) It is not safe to operate this set until these components are replaced with safety compliant components.

You need to decide if you can replace ALL the electrolytics and paper capacitors, probably most if not all the small carbon resistors, and clean up the switches and connections. If you want to, you'll have a nice set in the end, and we will help you get there.

No meaningful fast track for this, IMHO.
