Hello, I have one of these in my collection, I had to make a similar repair, then it worked quite well. It's a decent DXer. Thanks for the transistor radio videos, I really enjoy them.
This was likely a high-end receiver in its time. I noticed that it appears to have a ceramic tuning capacitor. The quality is definitely there in the cabinet styling, and it didn't take much to bring it back to life even though it is about 57 years old.
You can get low-voltage spot welders for about $50 these days. The target audience is people making battery packs, but it would do this sort of thing too. If you need it often enough, might be a good tool to get.
Real nice repair using a capacitor discharge spot welder. If you run across a radio with no model number on it search good old fleabay for the radio and someone will have the model number or a photo showing an intact label with it. The radio attic is another place to find model numbers matching the many photos of radios they have. Radio Museum is a good place to confirm it's model number. Not surprised it was made by Arvin. They made some spectacular looking futuristic looking radios in the late 1950's thru the 1960's. 50/50 mix of vinegar and water should clean the leather up quite nicely.
I like your use of a charged big cap to dump a high current into the spring. It really went well :-D (not something i would risk) ive had too many shocks at 240 volts. Maybe some wax shoe polish to make the back look better. And a cut down marker pen to cover the grill knocks perhaps. It does sound really sensitive, no need to touch any of the settings.
I don't remember seeing a small radio like this with a thermistor for regulation of the bias. That was not a cheap set I am betting. Did Zenith or anyone else do this in these small sets? Nice find. I would be curious to see what the ESR looks like in some of those caps, bet they are ok, but still curious me would want to know. I do have a MESR-100 meter, but I am thinking of getting a Capacitor Wizard, seems quicker than and easier to read than a LCD screen.
It appears to be a kind of USA/Japanese hybrid. The circuit board with its parts suggests Japanese, but the cabinet looks to be American. I've heard that Arvin did move much of its production overseas during this time period.
Without schematics its almost impossible to blindly troubleshoot these without spending hours of your life. Check voltages to FM oscillator and RF amps. Usually around 9-12 volts. If the AM works, there is s shared power supply so its more likely transistor failure.
Was wondering if you could help me fix a retro vintage style bar 8 track and record player, everything works on it but the fm, was wondering if you could help me out are lead me to someone who could fix it, I think it came from Kmart it was my grandparents stereo system can send a pic if need to
You should throw a set of eneloop 2500mah batteries so you don't have to open and close the radio every time you want to use it and not have to worry about battery acid. I keep low self discharge nimh cells in stuff like toys and radios I have. You can also use Panasonic blue carbon zinc batteries. I have never had one of them leak, but the potential is there.
Nice work! One of the handiest things I've bought at a swap meet is a small spot-welding machine, meant for dentistry (braces).

DAMN! Wasn't expecting it to work right off the bat! That's a testament to the old 60's - 70's capacitors!
What a nice radio and a great bit of spot welding.

Interesting! My dad had a Silvertone 1068 console record player from 1955. Never saw another in my entire life.
Nice radio repair!
Nice well-built Sears radio. I would spot weld the battery terminal like you did in a New York minute, easy peasy!
Congrats JP! Nice find!
Thanks. Saw it, and had to have it.
6 min in and I’m liking the cap and weld
That was really cool repair! I’ve heard that procedure could be done but until you, I never seen it performed.
Nice find! Looks a little like the General Electric "rifle" radio. I had an Arvin 8 transistor radio with the same case.
nice repair on the battery terminal. i was thinking that hot glue might work, but that welding was cooler
Great welding job!! Them die cast chromed radios usually are indicative of a quality radio.
I need to go to estate and yard sales more often.

That is a nice looking radio. Estate sales apparently have not discovered eBay type pricing yet.

Thanks for the sparks.
Interesting welding technique, but it worked. Decent radio.
I've Seen 1930's Silvertone
Radios & They Wh'er verynice Radios.

That is very Arvinesque, I imagine they made it for Sears.
Definitely an Arvin-built set (132 chassis prefix).
Nice radio!

It’s a vintage koronette console stereo bar would love to get the fm on it working thanks for any help

Did you noticed it used the good Foster brand speaker !
Arvin was based out of Columbus, Indiana.
If you wanted to make a series of show and tell vids of some of your radios it would be cool to see. Just sayin'.

Are you going to post up a few vids soon?
Working on it, but recently my car got plowed by some dildohead so im having to deal with thet meas right now

So far the fuji made amazon batteries have been good to me.
I Had The Same Issue With Wires That Wouldnt Solder Tpgether
So I Used A Little Flux
I've worked on 110,000 volts. I regularly work on 400 volts I hope I'm qualified
My hats off to you. You a lineman?
Larger sister for work I said I would like to say silver bottle
Did You Find That At A Garage Sale?
Wife found it on OfferUp i think
Bahahahahahahahahahahahahahaha!!!!!!!! BOOM! 🤣
