Arvin Twin Speaker

Post by Guest on Fri Apr 05, 2013 7:34 pm

I did pick up this 1957 Arvin radio today;
ARVIN INDUSTRIES INC. TUBE RADIO MODEL NO. 3561

6 tube; 35W4, 50C5, 12AV6, 12BE6, and two 6BJ6's

Nothing special, it just caught my eye and the plastic case is in nice shape.

I wouldn't say nuthin' special... Cool

Twin speaker, cool "tone register dial" and it's a 6 tuber---meaning it has a RF amp stage....it will be a hot performer if restored properly!

Personally, I think two is always better than one.

And, I agree on the rf stage. Especially if it's tuned.

I was just thinking about a radio like that last week and decided I wanted one. I didn't think I would find one this quick. Next, I need to find the time to work one a few of these finds.

Sometimes 6 tube radios have an audio driver added and use two finals in push-pull audio or parallel so there is no added RF. stage.

That partiular radio uses the 6BJ6's for an RF amp and the IF amp. It has no extra tubes in the audio. It should be a hot performer when it is restored properly. Have fu.

Yes, I checked the schematic when Cliff first pointed out the possibility that it might not be.

Very nice. I like the unusual dial scale for the tone.
Arvin made some neat radios.

Very unusual styling for an Arvin but cool. I like the tone and station locations.

Tony, I picked this up in a little shop on Rt.11 in Verona. I'm sure you've been there.

Nice looking radio. Not bad for an Arvin.
Reminds me of an AM-FM Airline I own.
Unusual style case. Push button opreration, speaker on top sticking out. Bottom front is volume control, dial, and, tunning.
It's actually got fairly good fidelity.

Yes, i know the shop you speak of. I also go to the "Factory" in Verona although its been some time since i've been to either one. Waynesboro has a couple of shops with the best one being Laynes on N340.
Looks like the Arvin has a nice set of speakers for a "twin" set-up as most of them had smaller speakers. It should sound nice once its gone over.

I checked out the schematics for this, found it in the 1957 Beitman's.

This is actually a very nice set. If properly gone-over, it will not only pull-in the distant stations thanks to the tuned RF stage, but sound great as well!

It also has a dial light to illuminate the scales, a phono jack input and a 3 section electrolytic for filtering.

Nice score Very Happy

I had to bundle with a couple other items to get it down to $15, but I think it was worth it! Very Happy

I finally got a chance to start working on the Arvin and what a pain in the butt it's been so far. It was completely dead and would not come up on the variac, so I decided to check all 6 tubes. No problem with the tubes, so I checked the switch and that was OK too.  Well I decided it had to be an open trace on the printed circuit board but that checked out just fine as well. Then I decided to do a volteage check from one side of the plug through each tube reading source voltage until I hit zero. THE TUBE SOCKET IS BAD!!! I'm going to try and repair the tube socket because it has an offset on all pins. Where it solders into the printed circuit is a larger circumference than the circumference of the pins. I hate PCB's and I hate these tube sockets even more!

May I see pics of bad socket? There's a slight chance I may have one. I do have some PCB sockets.

I have a few sockets i could pull out of a junk chassis. They are black plastic from the 50's. However they were not for a PCB radio but still may work. I have some octal,7 and 9 pin mini sockets.

I've found this material to be handy to repair torn broken or lifted traces on PCB's.  
http://www.amazon.com/Copper-Foil-Tape-CR-Laurence/dp/B006JCLODA/ref=sr_1_29?ie=UTF8&qid=1378069648&sr=8-29&keywords=copper+tape

Also, this old thread of mine shows how to make a manual solder extractor clean out discrete PCB solder connections, with less afterwork or reheats. Flux is also a must.

This was not damaged at the circuit board trace, the socket itself was bad. I did find a 7 pin socket that will work.

Thanks to all.

Glad you found a socket that will work. Good luck on restoration.
Please keep us informed................

I exercise every "good" word I know when I have to change a tube socket on a PCB. Good luck.
