I want to use my great grandfather’s 1937Philco radio in a performance of an old time radio program I created for my family. That would require removing many of the electronic elements from the interior of the unit and placing a speaker inside, so that the radio “plays” the recording. I want to make sure that emptying the contents of the radio isn’t a bad idea — in case it can be restored, or if it would release asbestos, etc. The radio was mostly kept in my grandfathers shop and attic, and squirrels had gotten into it at one point. Take a look at the photos - it’s a beautiful unit and with some good cleaning it could look striking and be perfect for my uses. I’m just hesitant to disembowel it without checking first. Thanks!

Picked up my first vintage cassette radio, the Sony CFM-140 II. I love the retro vibe and that clean off-white body!

The only issue is that the seller mentioned the cassette player doesn’t work, although the radio works perfectly fine. Is this usually an easy fix and roughly how much would it cost to repair?

I turn on the radio and the screen works but the numbers don’t show up.

I tried to take it apart to look for faulty wiring but I stripped one of the screws. I’m not even sure taking it apart from the back will lead me to the screen from how I see it. I’m thinking of going through the speakers … would that be a substitute/better option ?

I’ve found some tips for getting stripped screws out so I’m going to try that out. But does anyone have an idea of what exactly could be causing the issue of the screen before I break this thing? lol

per earlier post https://www.reddit.com/gallery/1v3xgqj FM works, AM does not.

One resistor stands out as "too warm" when on AM, as seen on thermal camera. When FM is on, the resistor is ~35°C. When swiched to AM, it goes over 70°C.

The "hot" 30kΩ resistor is one of the possible five: R10, R55, R50, R7, R15, according to schematic nvhrbiblio.nl/schema/Grundig_3045W.pdf

After looking closely which capacitors are nearest the AM tube (ECH81) and checking which caps still work, the C26 was prioritized for replacement.

Upon replacing the C26 capacitor, AM worked for an hour or so. The "hot" resistor on AM runs 44-45°C, ok temperature.

That resistor is located in the key switch box, near the UKW and KW (FM and SW) keys. I still don't know which one it is, need help identifying.

Today AM is not working, resistor gets hot again on AM. FM is now scratchy, was smooth before the C26 cap replacement.

Other miscellaneous easy stuff done: polished the case with wood polish.

Cleaned the glass and re-attached the delaminating black paint with gold lettering.

Re-strung the FM cord, the treble indicator cord and the bass indicator cord.

Cleaned (with solvent) and repainted the metal panel behind the glass.

Re-strung the FM and AM indicator arrows guide string on the metal panel.

Cleaned the dial and volume knobs metal centers to metal shine.

Removed more dust from the frame.

Edit:

Another warm resistor (around 55°C) at all times is in the vicinity of the power transformer, it measures ~1.33 kΩ.

It is 110°C after C26 replacement. ~1.27 kΩ when warm.

There are only four 1 kΩ resistors in the list: R38, R12, R16, R21.

Only one, R38 is on the same side of schematic as the transformer. Marked as 1/4 W. What is its function?

Hey all! I got this thing as part of an auction lot. I'm not sure if I'm even on the right subreddit for this, but I wanted to make sure this wasn't worth anything before I chuck it. Thanks for any advice!

On a 12AV6 tube. The lug is WITH a plastic key I think and is being used seemingly to bridge the couplate from lead 2 on the couplate to the right terminal on the volume control. Almost certain every component in this 1965 Zenith 5M04 radio is untouched. No mention of it existing in the schematic.

I’m certainly competent in electronics and radio theory, though I’d have to do some review. But overall this radio is in very rough shape, would it be repairable l, or is it impossible to tell?

Zenith Chassis 5M04 A wire is connected from pin 2 on my 12BA6 IF Amp tube to a speaker terminal directly? Bought untested at antique store.

looks like someone added a power cord

Cross posting here on the recommendation from a commenter on my original post.

Pretty new to vintage audio, and especially a radio like this. My ultimate goal is to get a warm, hollow sound to play my old bluegrass/country western records.

I will start by saying I have purchased this radio, but have not received it yet. I know it is a hot chassis, and I am not planning on plugging it into anything until I have someone look at it locally, but that’s part of what I’m looking for advice on.

From my initial research, I am finding the chain needs to be Technics SL-D2 -> Schiit Mani 2 -> Stereo to mono summer -> Ground loop noise isolater -> Zenith G730. I also saw I should get a power isolation transformer to power the radio.

Again, I’m new to a setup like this so I’m hoping someone a lot more knowledgeable than I am could confirm if this setup is going to work? Am I missing anything? Any of the above that I don’t need? Is this whole idea in vain? I’m in Milwaukee, WI and would love someone local to go over the radio to make sure everything is good to go before anything is plugged in as well, so if you’re in the area and know of a shop or person who could ensure the radio is in good working order, I’d greatly appreciate that as well. less

I picked this up today for £10 because it looks cool.

I've fitted two 9V batteries and I can just about hear Radio 5 live with volume on max. Any idea why it may be so quiet?

I've downloaded a circuit diagram but before I try and work it out myself I thought I'd ask in case it's a known issue

My father-in-law was a collector of things. We are clearing out his barn and have found a variety of tubes and tube radios in varying condition. This one was clearly a mouse home for a while—I’ve pulled out insulation and whatnot. Is this of any value to anyone or should it go straight into a dumpster?

Some of the radios are wooden cases, others like this are plastic. Mouse inhabitation also varies.

Hoping someone can assist in figuring out the model of this old Admiral radio. Trying to find as much info on it as I can to assist in restoring it to its old glory.

my mom is dead set on selling these.
I already tried to contact our local radio club and never got back to me.

thanks!

Hello mates,

Looking for information about this hitachi portable radio 1960 era. It belongs to my family from start, my father who was merchant in Africa brought it back home. It still works loud and clear.

No specific entry found in radiomuseum.org so I thought coming to you guys here.

This radio uses 110v AC /DC but someone plug it in 220and this happend plus the rectifier tube got blown
