Adding the resister to the power supply would not have anything to do with the fact that AC used to be rated at 110 v but now is rated at 115 to 120, would it? I realize that the cooler operation is a plus but I was wondering if higher modern line voltage entered into your thinking...
It would be in the later part of the 1930s 1936-9. A lot of radios at that time ran on 110-115 VAC so a dropping resistor is a good idea. As you know paper capacitors are always a problem but the distortion could be a bad audio tube/s. Thanks!
Beautiful old radio. The scale with colors looks very modern, compared to the inner side with the tubes. It is a unique combination, I think. A good idea to use the dropping resistor, it "takes" the heat and saves the tubes.
Thanks. The color in the dial is unusual and pretty neat looking. I want the radios to last as long as possible. Lowering the voltage just a little will help. Any heat dissipated by the resistor is not in the radio's components. Most of these radios were built to run on 110 to 115 VAC. Thanks again!
I was preparing to sleep and I was going to turn on the tv to see... well probably killings... very sad. I turnerd de notebook on instead and here the priveledge your video.
I will sleep calm and happy. I was able to watch beautiful stuff on the video. My dear Richard McWhorter thank you very much.
That's a great find! It's nice that it was such an easy fix; that doesn't happen many times. Just wondering: I have a Motorola 7VT5 TV that needs new filter electrolytics. There are 3 of them: one has 1 section, and the other 2 have two sections. That makes 5 total, but 2 of the values need to be made with 2 capacitors. So should I try to fit all 9 replacement capacitors under the chassis, or remove the original ones? They are riveted in place.
Wow that's a sharp looking radio! when I replaced the big electrolytics in my philco I actually cut open the can, removed the old innards and replaced them with modern caps, then sealed them back up. a little more work, but it was well worth it. I have 2 questions: 1. should I add an 8ohm resistor like you did in my radio? and 2. it's possible to get an accurate resistance measurement without de-soldering the resistor, right? or do I have to disconnect one of the leads?
I do that to and it depends on the costumer. 1. I do that when ever I can and if it does not degrade the performance of the radio. It will run a little cooler. 2. Yes it is possible to get an accurate reading but it does depend on the circuit the resistor is in.
If the resistor reads to high it's bad. If the reads to low then I look at the circuit to see if there's another path across the resistor, if so then it would be necessary to unsolder one lead. For sure if you unsolder one lead you will get an accurate reading.
If you are going to play the radio an hour once a week or less, it may not matter. This customer plays his radios for hours and hours many times a week so it will help keep the radio running a little cooler. Before installing, test using alligator clips, it does not get to hot, the radio plays the same.
Very nice radio...just my type. I like how you handled the e-cap replacement. Great idea. I've not yet had to deal with that style of can, but now know how to do it the easy way when the time comes.
Very nice looking radio, the cabinet is in such good shape. That epoxy trick really sounds like a good idea! That way you don't have to mount an entire new terminal yet the old cap is isolated from the circuit.
Oh it is a beauty. Thanks. I thought you would like the epoxy idea. I use the 5min setup. After mixing it up you put a little on each surfaces and when the epoxy starts to harden then you fill in the gap. Takes a little practice but it works pretty good!!
Where did you find such a nice set? It sounded like your tone capacitor was about to give out as well in the beginning. I have never seen Ecaps in a box like that. Do you just replace the resistor that are out fo value? I find if yu replace all of them, the radio will sound considerably more crisp and clear.
This is a customers radio. I checked the resistor a they were good. But if they where out of tolerance they would be changed out. You are right the best thing would be to replace all the capacitors and resistors and I would add a full set of new tubes too. This is a very beautiful radio and Im glad I got to work on it. THANKS!!
Speaking of rare, I have a 1956 Gellard record player that I need to finish working on it. I replaced most of the necessary components in it. Only problem now is that there's a wire wound resistor that doesn't have the value printed on it and it looks like it needs replace because the shell is degrading and it's expose parts of the element too. I did check it with a multimeter, but I'm not sure if itz out of tolerance or what.
If the unit operates correctly the wire wound resistor is good so measure the ohms. The watts you can judge by the physical size. If you guess to low the resistor will over heat and then you replace it with a high watt. BTW that was a very neat Russian Turn Table video!
What kind of antenna did you use to pull in the shortwave stations?

Yes, a lot of radios in the 30s ran on 110 to 115 VAC so a line dropping resistor is a good idea.

Thanks! I have a couple of 30s radios that I hope to tackle "someday" and will use the resistor in the line. This is a great tip.

Thanks Mario. It is a very pretty radio. It has seven tubes and all do something. The radio performs nicely.

Sadly this is a customers radio. I would replace all the E Caps and if I had the room would leave the old caps in place but not in circuit. Thanks.
