One day I was doing brakes on my car and brought my trusty Zenith Royal 500 to listen to the ballgame, and it was all noise. Huh?

After the brakes were done, I threw the main breaker on the house and the noise all went away, and the Zenith performed perfectly. I shut off all the breakers in the panel, turned on the main, and started turning breakers back on. I found several sources of AM noise in my house: the wireless router was the biggest offender, but also my outdoor motion light fixtures were making a big racket. There were a few other sources that weren't as bad but still existed.

I'm going to try an extension cord from my basement to the Radiola with all the breakers off (maybe Sunday) and see how the old girl does with no interference.

As for your IF coil, you're probably going to need a donor.

If the ferrite slug cracked cleanly and in one piece, some cyanoacrylate glue (tiny amount!) can glue it together.

If the slug piece is crumbled, you can try filling the crack with a *tiny* amount of *slow* set epoxy (the 24 hour kind). Use the tip of a needle under an eye loop and work a bit into where the ferrite top cracked to rebuild the slot.

In either case, the proper size adjustment tool is critical. If the tool is too small, it will put a point load into the gap and crack it.

I'd start dealing with that by replacing the power brick on the router and those motion sensor lamps with different brands.
