A wire wrapped around a capacitor that goes from one end of the cap to chassis is a choke. It was there to keep signals from maritime AM broadcasts from overloading the signal path in AGC circuits. Those maritime radios don't exist anymore as they broadcast in the FM band now. It was found in many radios back then and can be replaced with a ordinary cap of the same value to chassis ground. Mr. Carlson didn't even know that but I did. Thanks to my grandpa for telling me that when I asked him some 50 years ago. It is on the diagram as C 27 with the coil as L2 and goes to C28 to ground.
You've got a VERY INTERESTING radio video 📻 📹!! There's something about these old wooden radios. Quality went into them, and they were built by proud 👏 American workers. Just turning the volume knob on, and waiting for the radio to warm up was the best part. The glow (and the smell) of the tubes. The warm sound they produced. It was GREAT, listening to the ball game 🏑. These were functional pieces of art 🎨. Not Walmart garbage of today. The worst kind of capacitors in these is the bumblebees. They leak an oily like matter, and go POP!! It is best to replace bumblebees with capacitors that are less prone to going POP!! Just subbed!! Your friend, Jeff!!
You may have noticed this upon editing, but if not: @10:05 on the 30µF cap, your cap tester is actually showing 22.3 *nano*Farads, and continues to display nanoFarad values on all the other sections of that filter cap.
Did you check for continuity through the radio? This sounds like maybe an open switch, or an open tube filament. How about the switch that determines if it runs off the battery or the ac line?
First time i watched a video on your channel and I like the content but would you please leave out the elevator music ? Subscribing and serching for part 2. I like this radio and your choices for refinishing the cabunet.
I like the music you’re playing in the background. It’s nice.
Music like that can be relaxing while working.

Thanks for this! And thanks, Grandpa Master Nipper!
Hi,
Your radio restoration/repair is progressing nicely.
I will now view Part 2.
Thank you.
Best regards, PB.

I agree with everything you stated. Do what we can to keep these old radios alive.
Philco made valve computers too..... boy they were BIG.
멋져요...
That's interesting. I see it on the schematic. Thanks for your input.👍
I agree if you loose music that would be great
Beautiful🌹 and🌹👍
glad I'm not the only one who wrecks speakers! haha😂
I actually like the music. What kind of dispenser is the alcohol in?

Anybody know what size speaker is is in there? I'm waiting on on a partial one of those
I'd like this video better without the repetitive music. Otherwise, good. Thanks.
