Hello, total noob here. Please forgive any knowledge gaps!

RCA Victor 3VF226: I replaced the idler wheel and stylus, as well as cleaned the cartridge. Everything worked and I was able to play records for about 20-30 minutes. Sound quality was surprisingly good. Then after about 20-30 minutes I noticed the wood beside the turntable become very warm to the touch. This was accompanied by a screeching/screaming sound.

Reddit directed me here. The general consensus was that the caps and tubes need to be replaced. Any thoughts? Is this something I can DIY? Reddit seems to think it’s too dangerous for me to handle on my own.

Does anyone know where I can find the manual?

Would be grateful for any tips or help!

First--Do you have any experience in electronics? That will help us figure a path to take for the repair.

No experience.

I’ve been scouring resources online and watching a lot of videos. Paying extra attention to safety protocols of discharging. I’m debating if recapping is something I can handle.

We can't predict if you would be able to do this---and Reddit certainly cannot either.

Post your location and we can tell you where to get local help.

As for assessing whether you can do it, start by describing your overall experience with mechanical or electrical things, use of various tools, etc. Once we understand what you DO know, it will be easier to project

Putting aside my ability to do this, does any one have any ideas as to what might be the problem?

I’m just looking for knowledge. I didn’t expect to get shut down so quickly. Even a few ideas as to what might be wrong would be appreciated.

I have a vintage repair shop on standby. But more so, I was just curious to learn.

At least Reddit gave me a list of resources and ideas. This forum doesn’t seem welcoming at all.

BTW, welcome to the phono forum on ARF.
And actually, yes we are welcoming, but we have to work
with good information, so as not to ever guess or give a wrong
suggestion.

Re: what kind of failure happened to your RCA.

What someone should have told you wherever you first
posted, was to NOT power up vintage electronics
before they have the electronics serviced.

It could be failed resistors, filter capacitors, tube short,
transformer short, that is, many things or combinations.

Basic service for these vintage electronics includes:
1. Visual check out of radio and amplifier circuits.
2. Replace all filter and wax/paper or similar capacitors
3. Check power and output transformers for function
4. Check all wiring connections within cicuits.
5. Test vacuum tubes for functionality
6. Check all resistors to be wnl of their ohms value.
7. Record changer should be taken out and thoroughly
cleaned of all old grease. Motor mounts replaced,
and motor bearings and rotor cleaned and lubed
with turbine oil.

We will be happy to supply schematics for circuits
and the record changer.
Here is one schematic reference for Beitman's Radio Diagrams
from 1963:
https://www.radiomuseum.org/r/rca_3_vf_ ... qu_ch.html

If you don't want to take on this project, which is
pretty big for a new person, get a competent
person to do the electronic & record changer restoration.
With the right repair person, your investment
will last many years.
Best,
Hotwax

Yesss! Thank you, Hotwax!

I just want the opportunity to learn and gather info, regardless of whether I make an attempt or not. I fully understand and respect that there is a level of expertise needed in working with these machines. But everyone starts somewhere, and I love studying new things.

One other idea is to search for a local vintage/antique radio
club in your area.
These can be a great resource for learning or finding repair persons.
Many offer classes, too !

Learning is always good, so good luck on your efforts,
and come back with more questions.
We (for the most part) were all newbies here, once.

What?? No-one here has been unwelcoming at all---just asking questions to get acquainted...

Was it Reddit that told you to "replace capacitors and tubes"? Whoever said that gave you bad advice---tubes are just about the last thing to worry about--I don't even test them till everything else is done.

Hotwax gave you a good list of what needs to be done. With record players, I normally do a complete disassembly and cleaning / lubrication.

The filter capacitors are old and dried out. They become very leaky and pass AC into the DC power supply. This will heat up resistors and is the heat you feel. The noise is telling you power supply problem. The tubes are taking a beating as well as other parts. When replacing filter capacitors it's best to replace all the paper and wax capacitors as well while your at it. This will make a trouble free record player for years to come. A cheap repair for now. Capacitors are cheap. Don't play it again till this is done.
