On my last trip to Beltsville, MD, I acquired from John (Combo52) (Thanks John!) this beautiful radio. It's a mid-range model. The lower model had no doors. The top of the line had a phonograph. Walnut veneers. These radios even came with an optional remote control. Ironically, at the time, RCA did not manufacture it's own radios, but farmed them out to various manufacturers. This particular model was made by General Electric. The General Electric equivalent is Model H-51.

 

The first batch of images is when it had just arrived to Brooklyn:

 

RCA7

 

RCA4

 

RCA5

 

RCA6

 

RCA1

 

RCA2

 

Second batch it was cleaned up a bit with Gojo. That stuff does wonders. I already have the schematic and ordered a variac. Currently sporting some Christmas cheer.

What a beautiful radio Louie! Those vacuum tubes look like they are the originals.

I just love the warmth of the sound that these old vacuum tube radios produce. The way they warm up and the sound takes a few seconds to start to come out of the speaker. I gives meaning to the song, “Coming to You From Out of Nowhere”, and now I’ve just really dated myself for even knowing of this song.

Does it actually work and pick up broadcasts? From the look of it, I’m betting that it does.

Hope you are enjoying it.

Happy New Year Louie!

Eddie

Beautiful radio! I love antique electronics, I believe these were marketed by Victor, and that is the reason that the electronics were manufactured by other manufactures. A friend of mine has the model with the phonograph in it. Do not know what brand the radio is, but the phonograph is an acoustic Victor with an electric motor. The motor is really strange looking. It is an "open" motor, and looks like an electric meter disk, with a coil on one side.

Thanks Eddie! It's currently not working. Missing a vacuum tube for starters. John had mentioned it used to work. I plan to fire it up with the variac. Have a very happy 2020!

Thank you Rick! RCA Victor manufactured it's own first radio around 1933. Happy New Year!

BEAUTIFUL!!!!!EXCELLENT SHAPE ITS IN!!!!Got lots of care over its life.A man that used to work at the transmitter plant with me collected old radios.He retired many years ago and moved back to Tennessee-his home state.Is this radio AM broadcast band only or does it have short wave bands?If it can receive SW you could hear VOA/Marti in Greenville with this radio.

This particular model was made by General Electric

 

According to Wikipedia, RCA was owned by GE at the time. Quote:

 

The RCA Corporation was a major American electronics company, which was founded as the Radio Corporation of America in 1919. It was initially a wholly owned subsidiary of General Electric (GE); however, in 1932, RCA became an independent company after GE was required to divest its ownership as part of the settlement of a government antitrust suit.

 

en.wikipedia.org/wiki/RCA...

 

So it's not surprising that GE made RCA radios at one point.

I think some must be replacements. If one looks at the maker names on the tube bases, one will see that there is a mix of names.

 

I played a bit with tube radios when I was younger. It was amusing seeing labels in the radio that always said to use tubes from the radio maker. And yet, there might be no single tube left that was branded with the radio maker name!

I just love the warmth of the sound that these old vacuum tube radios produce.

 

Tubes remain very popular in some audiophile circles. I think "warm sound" was one argument, although people with more experience than I have indicate that many tube amps have become more transistor like over the years. (Yes. There are still tube amps being made, although they are not exactly cheap.) Meanwhile, many transistor amps have become more tube like than was once the case.

Thanks Rex! The finish does of course have it's issues, but nothing major. No cracks or missing veneer. Gojo took decades of grime and old wax off.

Thanks John. It's my understanding General Electric bought RCA back in 1986, that it was owned initially by General Electric is news to me. RCA Radiolas also had it's radios made by Brunswick, Westinghouse, Graybar and others until 1931. Indeed, most of the tubes have been replaced. It would be amazing if it had all it's original tubes.

The article on Wikipedia mentioned GE buying RCA in the 1980s. Coming round full circle for RCA, I guess...

 

Yes, it would be surprising if all the tubes were original. I'm far from a radio expert, but I've seen a number of old radios, and almost always there is a healthy mix of what are clearly replacement tubes.

I didn't know about the GE/RCA connection until reading this thread :) really cool old radio-I have a few from the same era.

before you bring up on a variac might be good to replace any suspect capacitors (called condensers at that time) as at least some will probably be leaky unless John or someone else did that already. Radios of this time had potted transformers and interstage transformers, chokes, so were more complex/expensive in a way, later circuit designs eliminated them to save cost. The electro-dynamic speakers as seen here were typical; permanent magnets with enough power hadn't become affordable/available yet. Tubes in sets like these tend to be available and fairly reasonable. Looks great and fun to use and enjoy!

Yes. This is possibly already known, but this is worth mentioning. It seems like most people into radios now just automatically replace any failure prone parts before doing anything else. The thinking is: if the part hasn't failed yet, it probably will fail soon. And doing this may just fix problems without having to actually diagnose them.

 

A link to some talk on this topic:

antiqueradio.org/recap.htm...

Interesting, and something I'd suspected/been wondering about--if radios didn't have an evolution that allowed cost savings.

 

(Although I knew for sure of one cost saving approach that came along later: the AC/DC radios that eliminated power transformers.)

Old Radio

combo52's profile picture

Yay Louie I am glad you are able to give this radio a good home.

 

My first partner Michael found it at an antique store almost 40 years ago, it was working when we got it and I used it many hours.

 

When Ken moved in two years ago we got rid of all the old Victorian furniture in the living room, its kind of funny when I was in my 20s I though it was kind of cool, but in reality it was never my style.

 

Before we moved it into storage a year ago I turned it on and it still worked, it only seemed to get 1 or 2 of the stronger AM stations however.

 

The tube that is missing is a rectifier tube, it has more than one and it has never had one since we owned it, If you need any tubes for this radio I still have boxes of them that were collected when I was a kid, I used to love collecting and fixing old radios and B&W TVs.

Interesting seeing all the new photos!

 

One point: from what I see, the missing tube is an an amplifer tube, not a recitifier.

 

I once had a console radio (not this old, and certainly not this interesting) that also had a design with two amplifier tubes, but only one still present when I got the radio. It worked--although the radio wasn't in peak condition. Then, that's not surprising for something that is decades old!

loose wire is for the dial lamp-looks like socket may need repair.

I feel that way, too, about Victorian. I can appreciate it at times, and once thought I liked it--but it's not my style. At least, not now.

 

I also have had the thought that I have liked Victorian better in imagination than reality (e.g., imagining Sherlock Holmes in a sitting room full of Victorian is more fun to imagine than to live with!).

You're correct John, the UX-245 is an output (amplifier) tube.

missing tube...

firedome's profile picture
45 tubes - UX-245 is an earlier "globe" version - have become cult objects among Japan and Hong Kong's single-ended audio fan-boys, hence prices have skyrocketed in the last 25 yrs. ST "shoulder" versions of the 45 were fairly commonly used in radio amplifier circuits of the '30s, and are now sought after by fanatics for low power boutique tube amplifiers

Post# 1056688 , Reply# 23   1/6/2020 at 10:08 by kenwashesmonday (Haledon, NJ)        

It will play with only one '45 output tube, but it won't get as loud or sound as full.  

 

Bob Dobush at findatube.com has good prices for tubes.  He as used 45 tubes for $18 and new ones for $41.

Thanks for the information guys. However, I could not find any UX-245's listed in Findatube.

The "2" in 245 only refers to the manufacturer of the tube.  What you want / need is a "45" tube.  A good used one should be fine.

Really great pictures, enjoyed them.

 

This radio could be delivered to your home for $206.50 according to this ad from the Nov 28th, 1930 Madison Wisconsin State Journal.  That's $3,238 and change in today's dollars.

UX245...

firedome's profile picture
the original globe style version is available tested/used on eBay, here's one pair available:

https://www.ebay.com/itm/2-Globe-45-RCA-...

The later ST "shoulder" configuration of the 45 is the same tube, it's not cheap either. Emission Lab has put a new version into production for the die-hard audiophools, , but you don't even want to know what those sell for:

tubesusa.com/ELtubes.html...

I'd just look for a good used ST type 45 tube, that radio amp probably wouldn't require a matched pair so you can just look for a single. I had one kicking around a couple years ago but not sure I still have it... will look.

Radiola

What is the story of the brand name "Radiola"?

 

Here in Australia the name was associated with AWA - Amalgamated Wireless Australasia.

we had an AWA Radiola record player when I was a kid.

AWA established a joint venture (Amalgamated Wireless Valve Co. Pty Ltd) with Radio Corporation of America (RCA), to manufacture radio valves (vacuum tubes) at the Ashfield works under the AWV, RCA and Radiola brands.

Nice Power Cord

combo52's profile picture

Hi Louie, It looks like progress is being made.

 

Nice Variac , these are a good idea if you are powering up old electronic equipment that has not been turned on in a long time.

 

It might not make any difference with this radio as we turned it on and let it play for at least a 1/2 hour not that long before you got it after it sat for at least 10 years without being turned on.

 

Interesting that the new power cord looks like it is polarized so it is not an exact reproduction so you could lose points at the judging, LOL

 

Keep up the good progress, John L.

LOL John!

ultramatic's profile picture

 

 

I think they only come polarized. Besides, if adds to the safety factor that's fine. I know All American Five's from the 40's and 50's really need these plugs in order to prevent a "hot" chassis. I don't think the Radiola would need it since it has it's own transformer.
