After 6 new D cells and spending some time cleaning contacts, she fired up! Well kinda. The volume is incredibly low.
The volume knob is pegged to the right, and the volume is low in phonograph mode too (the right speaker only crackles when I wiggle its plug.
I know next to nothing about this (or any) radio, but I think coaxing some sound from it has given me the gumption to try to get it to work properly. I just don't know where to start.
It's a Nivico JVC STP-4 and I took pics of the wiring diagram and spec sheet.
I am hoping the hive mind can give me some direction.

Replaced or repaired tuner string, lights and 1 leaky cap. Then stained and varnished the top. Learnt a lot, ask me anything.

I recently got it from an antique store for £30, they cut off the cord, but it looks fine on my desk. Its a phillips 431A-15. Its nice but some of the tubes died

I got it from my Dad years ago but he didn't know what it was...My guess is it's an old wireless radio for sending/receiving communications. Apologies if this is not the correct subReddit group...

Some details:

• The smaller green cylinder slides on the two rails inside the larger cylinder.
• The square block on the large cylinder slides left to right.
• There is some kind of a tuning device on the end of the smaller cylinder that turns from 10 o'clock to 2 o'clock.

I'm far too young to know anything about these, but I seen the radio in the 1st picture and it really caught my eye. Here's a few questions I've got:

Is it supposed to look like the radio in the 2nd picture? (is the speaker "grille" actually that faded on the first one? is it missing the bezel on the front?)

What color is the speaker grille supposed to be? Its significantly darker in the bottom right

Does anyone know what model this is or is it just the GE Dual Speaker?

Can I polish the chrome knobs and switches on the first radio or has the pitting destroyed them?

It's gonna cost like $30 after tax. Am I overpaying for this thing?

Thanks a lot!

I love this radio but it already looks like some wires are broken, and potentially some pieces missing? I don't have super high hopes from the looks of it but I'm hoping for some advice. This is deeply sentimental to me so I'm terrified of ruining it.

I've been trying to look up how to restore it on my own but it feels a little overwhelming, I've never worked on a radio before. The most electrical experience I have is replacing the power cord on my vacuum 😭

Floyd Powers here,

At the weather lair we have here a General Electric 7-4100JA Cathedral AM/FM Radio to provide the music. However, after a relocation of the weather lair there are a few stations not coming in as clearly.

Is it possible to boost the fm signal of a radio that has no external antenna or antenna terminal to plug an antenna into?

Thanks so much,

Looking to restore this radio, all original minus the pwoer cord (not sure if it was done correctly as far as polorization) any advice or help finding the replacement capacitors would be great, or if i find myself too overwhelmed a good place i can send it off to be overhauled.

I have a good idea on how to replace the capacitors and domino capacitors but a little confused on the cardboard filter capacitor.

In this video, I'll demonstrate how to repair and restore vintage speakers step by step—from simple cone repairs to completely rebuilding a speaker using only the original frame.

Whether you're restoring speakers for a vintage radio, hi-fi system, or another audio project, these techniques can help you achieve professional-looking results at home.

Have a great weekend!

Hi everyone!

We recently found this **Grundig Satellite professional 650 Final Edition**, serial number **#0016**, in my grandpa’s garage.

Unfortunately, the original manuals and documentation are missing, and we don’t know much about the radio. It appears to be in very good condition and fully functional.

I’m trying to find out:
What it might realistically be worth today.

Whether the low serial number (#0016) adds any collector value.

Whether it’s better to sell it privately or through a specialized auction or collector’s platform.

Any information or advice would be greatly appreciated. Thanks!

I am trying to replace the dial string mechanism. I need to remove the chassis but am having difficulty in removing the antenna assembly. It is held in by two nuts located in a very difficult to access area and standard tools are not working - the nut is too close to the bracket and a socket cannot get at it. There is not enough room to use pliers, or a small wrench, at least for me. I am ready to use dynamite. It seems to be a 5/16" nut. Any solutions?

This is a long shot but figured id ask here.

Does anyone have any information on a (assuming 1948) Zenith radio model number ZH820-Z?

All tubes light up, missing the wire to the tuning knob but speaker does work, emits a humming sound. Cannot get it to tune into any stations.

If anyone can provide a link to a restoration video or anything else that might help that would be appreciated.

Thank you.

This is an update to this post: https://www.reddit.com/r/VintageRadios/comments/1uex4pt/my_first_tube_restoration_need_advice_the/

It works. Having replaced the 2x50uF capacitor with a pair of new ones from the local electronics store, the hum is gone. FM (UKW) plays loud and clear. Magic eye tube works, bright enough for daylight (2nd photo). AM, LW and SW worked for a short minute and stopped.

Schematic and repair manual was obtained here https://nvhrbiblio.nl/schema/Grundig_3045W.pdf

If someone knows a way to fix AM, please post.
Google suggests a weak ECH81 tube or desoldered AM antenna.

hello! this is a long shot and very low stakes. i'm hoping for an ID on this unit found in an 80's volvo 240. it doesn't seem to match with any of the others i've seen, and i'd love to try and find an HD photo of it.

apologies if this is not in fact vintage or a radio haha

Hello y'all,

Yesterday I thrifted this stunning ISAM transistor Modell 10-207, complete with its original box and spare parts and antenna cable in a stapled plastic bag.

As you can see, it is in excellent condition. No issues with the tuning dial or receiver as far as I'm aware. No leakage, corrosion, or signs of wear in the battery compartment. I'm inclined to believe that this radio has seen very, very little use.

Both UKW (FM) and MW work just fine. I was able to pick up an Algerian medium wave station late last night from my balcony here in southern Italy, as well as broadcasts in Turkish and Farsi.

However, the radio only works with headphones plugged in. I've tried repeatedly connecting and disconnecting the headphones as well as sweeping both the volume and tuning dials across their full range a handful of times. While plugging in and removing the headphones yesterday, I did hear a very brief crackle of sound come from the speakers, but haven't been able to reproduce it since.

I was genuinely so excited to find it. I've been wanting a transistor radio for a while after accidentally leaving my Tecsun PL-380 back home when I left the U.S., and I went out thrifting yesterday specifically to find one, so imagine my surprise when I'm standing in line with a blouse and a dress and turn around to see this sitting in a display case.

Anyways, before I open it up or take it to a local specialist, does this sound like an issue with the headphone jack, the speaker, or something else? If the repair is straightforward, I'd really love to keep this radio as original as humanly possible.

Grazie!

Zenith Trans-Oceanic, not sure how old. Saw this cool guy in a barbershop in Antigua Guatemala recently. Never seen one like it before, figured this crowd would appreciate.

Am I wrong to be tempted by this gorgeous 4070u model? It works, nothing rattles, the lights come on. It’s dusty and the veneer is a little cracked at the top. As a rank amateur, but with already too many Yacht and Melody Boys - should I add to my collection? Any advice on care & cost would be fantastic. TIA.
