Edison Radio Parts

Post by JJSmitty on Mon Dec 03, 2012 5:53 pm

Hi All,
I am trying to help my Dad in identifying and figuring out what to do with an Edison radio (no cabinet) that was passed down to him from his Dad who worked at Bell Telephone in the '30s, who got it from a buddy who sold Edison radios.
Anyway, I've spent a lot of time looking around. I think they are parts to an R7 maybe. Would anyone be able to help me identify all these components? I have pictures but couldn't get them uploaded here.

Thanks a lot for any guidance.

JJ

That is not an R7. Not sure what model it is. R7 has green chassis, and, isn't built the same in power supply. Also, all, but, one tube in receiver chassis are no 27's, and, use no shield.
This is an earlier set. Perhaps for 30 cycle ac use.
If so, it won't work on today's lines.
Some areas at the time used different current, and, some countries still do.
Is there a tag on upper radio receiver chassis that gives a type number?
Do you have original speaker? That will be hard to get. An empty cabinet will likewise be hard to find.
This might be a better parts set, or a display item.
It may have other serious problems....
Looks like it was taken out of service because it quit working.

Edison radios were way ahread of their time. Great fidelity, and, very sensitive on reception. However, like all the radios of it's time, The capacitors were the weak point.
Very often the caps in the power supply shorted, and, the power transformer, filter choke, and, field coil on the speaker would go up in smoke.

Wow Bill, you certainly know your radios! Very cool! I will inquire about the speaker and the tag and whatever else my Dad may remember about the set.
I really do appreciate your input.
Thanks much,
JJ

No problem. I have collected Edisons, and, know alot about them, as I know how to restore them.
Always happy to help.

Bill, would that number be the AP10146 that I thought was a serial number? There was a photo of it. Or what kind of number would it be?

Thanks,

JJ

No. I think it was the serial No.
Edison used alphabet, and, single digit numbers on models.
R7 was a radio only.
C4 was a radio phonograph combination.
C1 was an early radio phonograph combinations.
That gives some examples.

Of course, it may have been a Canadian set, and, who knows?

Hi Bill,
Long chat with Dad and here's the history. His father's friend, Bill Neal was the Controller for Edison in West Orange NJ. He was relocated to Wisconsin to the Edison factory that made the cabinets for the radios. When he moved he gave this radio to my grandfather, and apparently as my Dad remembers, at the time it was working. The speaker was originally with it (of course) but is now missing. My Dad thinks he may have tossed it because the "paper" was broken.
He looked all over for a type number but only found a tag that reads 13141.
Anyway, that's the story.

Hmmm. May have been a Canadian number. It surely isn't built the way the 7R is. I can see that.
I'll look in my Edison litterature, but, I doubt it's in there.
I have the original factory info. on all, but, the early models of C1, and, C2.
Of course, I don't think my litt. covers the Canadian models.
There appear to be extra blocks on your power supply that make no sense, and, I don'[t see a hum balance dontrol.
Too bad your grandfather threw out the speqker. That part is nearly irreplaceable. I have one speaker for the R7, but, it needs complete re building, and, I don't know what yours needs to be.
It may be alot higher resistance fielld than mine.
Does your father have the cabinet? If not, it remains questionable whether, or, not it's worth fixing.
Further, most Edisons, the main radio chassis has the front panel attatched to it, and, of course, the special wooden knobs.
I might be even to rebuild the set, and, get it playing for you for a charge, but, I don't know what your father wishes to spend, and, it is likely to be pricey because of having to get the speaker re built, and, the cost of parts now.
This is not an advertisement, guys. Just an offer that I really shouldn't make. I want to help in any way I can, but, this radio is going to need alot of work. That I cqan guarantee.

Hi Bill, I did some research this morning and found documentation on the meetings on the 1930 radio designs (document #6 at: http://www.bentongue.com/edison/edison.html). On page 41 it states: the finish for the 1930 radio set will bronze - same as for the ER-5. Curious. Could it be possible that since Bill Neal worked for Edison maybe he had an early prototype? The paper goes on to talk about the bronze lacquer finish, Splitdorf doing the spraying until Edison could build a spray booth (p75). Maybe you have seen this document already. In any case you would know better... it has been very interesting learning all about these radios and I really enjoyed reading the meeting notes, felt like I was there. Seemed like they had a hard time being punctual because it repeated state "be on time". Funny.

No, I haven't seen them. I'll look. Thanks for the link.
Edison bought Splitdorf in 1927 to build their radios.
The Edison companny quit making equipment for home entertainment in 1929.
If that radio dates to 1930 it must have been for either Canadian use, or, some other special use, maybe at bars, or, whatever.
The Gold finnish was first used in the early sets in U.S.
Also on 110 volt DC only models.

Did you say bronze??? Not familiar with that.
That would have had to be a special set.
Is yours bronze plated?

This link works: http://www.bentongue.com/
Section B is all Edison docs, curious to see what you think, or if you've seen any of them before.
This set has a bronze finish, I wouldn't say it was plated though, and those meeting documents talk about a bronze lacquer finish...

The links aren't working.
Never seen a bronze finnish Edison before.
Interesting.

That's funny, wonder why, I clicked the link I sent and it went through. Maybe try typing it in the browser?

Or if you'd like I could email you the pdf file.

Also, I missed this before, page 5 talks as well about the finish.

Can someone mail me the pdf file?
Thanks. I can get to the site. That's not the problem. None of the links there work, and, something weird happens. Windows blocks an attempt for the site to run Windows media player.
Huh??????????

Yes, but, I wasn't able to look yet. I have the schematic for the R7, so I don't need that.
The advertising sounds interesting, as does the link for the meeting. Just haven't had time, yet.

This appears to be an R6 chasis. I could use parts for mine if you decide not to restore that one.

here is a pic for reference of mine.
