Part2 Antique Radio Repair 1934 RCA Model 262 part 2

Beautiful RCA 262 5 Band Allwave Receiver. Part 2
Doing some preliminary checks. Power transformer looks OK so far. I ran power to it for 10 minutes and got approprite voltages for the AC to the rectifier, and also got the 6.3 volts for the tube filaments and the 5 volts for the rectifier filament. Also ohmed out all coils and transformers.

Your variac, can I use a dimmer switch like you would use in a light switch. I.E. I would have a heavy duty extention cord about t 12" long that would be connected to a dimmer switch, that would be connected to a GFI outlet? The GFI would be for safety. What do you think. I also been tinkering with old radios...I have a 1936 Zenith 5S150 wooden consol an a 1953 Philco Transitone 53-561. I dig your videos, that an the library books on old radios I been reading have been a big help.

Wow! that's a really good question. I wish I had a really good answer for that. I guess check the package the dimmer switch comes in for intended uses. The radio like I have pulls about 1 Amp. I am not sure if the dimmer switch changes the AC sinewave form somewhat due to the electonics inside the dimmer. A variac wouldn;t change the sinewave at all. You have realy nice radios. Check out antique radios web site for the blogs. I learned a lot from them.

I gave it some more thought. I highly recommend a VARIAC plugged into an isolation transformer. The isolation transformer can help protect you from possible electrocution. It's better being safe.

So, where do I find an isolation transformer an a variac? I'm nervouse about ebay, cause I don't wanna buy faulty safety equipment?

[Lockemeister]

I got both my isollation transformer and the variac from 2 different vendors on Ebay. The isolation transformer was pristine. the Variace had a little wear to it and needed some repairs. The socket was worn and I installed a short pigtail and new socket. Try google or yahoo to seach for these things if you don;t wish to use Ebay. You might find new isolation and variacs on Ebay from reputable Vendors or at least get manufacture names and search the internent for those manufacturerers.

Cool! they are a few people on youtube that are pretty good at the hobby. check out allamericanfiveradio, he's a radio genious. I got a new video series too on a Philco 16B. Good luck with your radio hobby.

Thanks, Im gonna search for them.

Cool, I don't feel as bad about not having the original speaker now!

Dp you have any other tips you can give me?

I don't even know the questions to ask.

Actually I just thought of one. If one of the IF 460 KHz transformers turns out bad, coould it be replaced with a 455 KHz transformer? or is it better to bypass the transformer with a resistor and capacitor?

[AllAmericanFiveRadio]

If the power transformer is good there is a good chance that the field coil on the speaker burnt out, which saved the transformer. And that good.
