- The first power up after restoring my 1936 RCA C8-19 console radio. Song is "The Hut Sut Song" by Sammy Kaye and the Kaydets. The radio's chassis was rusty, and much cleanup work was required to make it look good again. All new electrolytic capacitors were installed in the set's original aluminum tubes to maintain a factory look. Underneath, the wax/paper capacitors were all replaced, as were the majority of the set's resistors. Much of the original rubber-coated wiring was rotten and required replacement as well. One tube, the 6E5 eye tube, was bad. An NOS Toyo tube was sourced on eBay, and as you can see in the video, it's VERY bright. The set's 6F6 audio output tube ran VERY hot, so it was replaced with a much cooler running 6V6, and sounds just as good. The set is being powered through a homemade bucking transformer to shed about 12 surplus volts from my AC line voltage. I run all of my antique radios off a bucking transformer, as my line voltage is consistently 11 volts higher than what these old radios expect to see. No work has been done to the cabinet, besides some cleaning. Next summer the cabinet will get some attention. The video caption says "7 tubes", but if you count the magic eye tube, there are actually 8 tubes. There are only 7 tubes responsible for doing actual radio duties ;)
even Bob Andersen would be impressed..i am..good job dude...
Nice! I’ve had one for year’s and I’m finally getting it restored! I cannot wait. The magic eye is beautiful.
I was really impressed with this unit's performance once it was recapped and aligned. I think you will be too. Just watch out for chafing on the wires going to the speaker through the metal grommet in the chassis. It was creating an intermittent short on mine that was tricky to track down. Wound up replacing all of the speaker/field coil wires.
The Radio Pleasure Palace thank you! I’ll pass your comment along to the guy who is going to be doing the work. What is the function of the far right knob?
@@scottlowery8947 Far right? That's power and volume. Middle is the bandswitch, and the far left was tone.
Beautiful :D
I re-did my grandma's C8-19. I love it. Did you end up replacing the long multi-tap voltage divider resistor? I didn't, and I still get some occasional static "tics", even with the volume down, that I suspect might originate there.
Do you have some sort of transmitter your using to feed it signal?
Did you ever get anywhere with the cabinet finish? Mine needs work as well.
Oh, and I think you'll find the left control is the volume, and the right control is power + tone (OFF + 3 tone positions). Before I recapped, the tone control had no effect, and without a label it was a real mystery to me why it had a four position on/off switch!
Hi Steve, no, the "Candohm" multi-tap resistor was fine on mine, so I left it. I know a lot of people advocate replacing them, regardless of how they test...something about the paper they wrap the wire-wound element in going acidic and eating through the windings...but I've never had an issue with it.
On your set, popping regardless of volume setting could be an intermittent in the Candohm, or it might be a mica capacitor going bad somewhere. You can power up the radio out of the cabinet, and CAREFULLY use something insulated to gently push around and prod the contacts of the Candohm to see if it's the origin of your noises. If it is, physically moving them around with the set powered up should cause the symptom to occur. Just be careful, you don't want to 'ride the lightning'.
I never got around to doing anything major on the cabinet. I did reglue some veneer that was lifting, but decided it didn't warrant a full refinish.
You're indeed correct, the far left control is volume. Mea culpa!
I feed my antique radios signal via an SSTRAN AM Transmitter connected to the computer.
