Good video! I usually place a coil of the end of the antenna wire across the back of a set with a loop antenna. Some of these sets have a capacitor already, going to the external antenna connection! Shows the importance of changing that one (I know a lot of restorers don't bother).
Nice to see ya again! That radio is absolutely BEAUTIFUL. It's design is sooo elegant.. oh man, I want one, and bad. lol. I love your videos. Really fun to watch, calming, and educational. Nice work OM :) Summer is here, and with the yard work, the helping of neighbors, the garden, my John Deere 318 project, etc... I also have no time to make a vid! And I'm RETIRED! So I know what you mean. We all do. It's crunch time in the 'states. We love your stuff. Don't feel pressured to produce. Family, friends, critters and the dang lawn come first! Thank you so much. Take care and enjoy the wx! Chuck
Great tip! Tube radios are vulnerable to all kinds of noise and I usually do this when there's a radio carcass under repair on the bench. I'm retired now, and I'm busier now then when I was working........
Great video! When you directly connect the antenna directly to the radio, what exactly causes the buzz and why does the capacitor eliminate the buzz? Thanks!
Very informative. That's a lovely radio - never seen one like that before.

Excellent video! congratulations! I think that this problem that you describe is due to the impedance of the antenna. If I do not remember more, in those times the impedance of an antenna was 300 ohms. In this case, capacitive coupling can help, and you can just as well use a balum or some RC coupling network. Thanks for sharing!
The last Zenith I had that quit working intermittently had a bad 50L6. After it was running a while, the heater would open, and as the cathodes cooled, of course it would quit. Then, the minute I started trying to figure out what happened, it would start working again! It sure took me a while to figure that one out! I look forward to finding out if one of the tubes has a low speed "blinker" for a heater!

That's pretty cool! Thanks for sharing.
Thanks for the video. I learned a lot. Great to see you. Take care 🙂

This one has a 35l6 as it's a tuned RF stage job.I haven't got a chance to mess with it but I suspect a flakey tube.
Do you happen to know what type of capacitor was used and where to get them? Thank you I'm very new at this and can use your help
Very interesting, I had no idea.
Good tip. Cheers 👍
Sounds like a hot chassis radio.
It's interesting and a bit strange because in most schematics the antenna is connected already though a capacitor...
Never knew this. Thanks. I wonder why
What capacitor you’ve used?
I would start with a 10nF capacitor... ceramic capacitor... non polarised.
