I just picked this radio and speaker up during a trip to upstate New York.

The radio is a 5 tube Silvertone (Sears) Neutrodyne made in 1924/1925. The speaker is a Saal reproducer. No tubes came with the radio.

There was even a letter dated 1925 from Sears to the original owner with operating instructions!

Nice and clean.

Nice! There should be a date on the C battery, so you can tell when the set was last used.

The battery has no information as to the manufacturer, date, etc.

Just the voltages and the initials RSYM on the bottom.

Probably a date code. I don't think I've ever seen a battery without a maker's name; perhaps it's the original one.

The documentation makes this a treasure.

Alan - I'm very confused about the tubes this radio uses. Can you give some advice?

Nice radio.

This set used the common UV-201A or UX-201A long pin version.

Actually, this is the less-common dry cell Silvertone neutrodyne manufactured by King. It requires UV-199 tubes (these have short nubs instead of pins):

http://www.radiomuseum.org/tubes/tube_uv-199.html

UX-199s with pins will not fit these sockets.

Image

Note that this set is likely to have open windings on the audio inter-stage transformers. You should check for this, and correct it if necessary, before investing in good tubes (as opposed to defunct tubes for display purposes).

Also, this set originally had a decorative pressed-wood trim around the periphery of the front panel. Since it needs to be removed in order to undo the panel screws, it is clear that this set was opened for servicing at some point.

Image

This set was sold with a set of Silvertone branded tubes, and a Silvertone “C” battery, amongst other accessories; I believe that a Silvertone horn either came with the set, or was an optional accessory. My example of this set has the original Silvertone tubes and “C” battery, and the latter has a date code of “TED 1”; I have no idea what this means, but the date should be consistent with the radio itself.

(The two ARF Gallery pictures above are of my actual set, and were taken from the eBay auction listing; I came upon them here some years after purchasing the set.)

By the way, one of the 199s in my set is cracked; if any-one has a Silvertone UV-199 for sale, please let me know.

Thank you for the detailed information.

I normally don't deal with battery sets. I found some UV199's here and see how they are the correct tubes.

Unfortunately, it seems that both transformers are open on one side.

As far as the decorative trim, the set came with the trim pieces for the sides (the shorter ones) but not with the longer trim pieces.

Here are some pictures of the chassis.

For anyone interested, I have posted a pdf of the original instruction sheets at the following:

Many thanks for posting those pictures, and especially, for taking the time to scan and post those splendid documents. I should think that those instruction sheets are quite rare. They, and the envelope and letter addressed to the original owner, certainly add a great deal of interest to your set.

My set also has open windings on the two transformers, which appears to be typical for this model. I have not yet had an opportunity to correct the problem; but you likely know of the various options available to do this.

A table-top neutrodyne for dry cell operation is rather special, and these sets by King were very nicely designed and executed.

An easy enough task to hide a "R-C" network in the set and keep it visually intact / original.

jonboy,
I'm not wanting to steal your thunder...
I too have the very same model as yours. It uses the 199 tubes. Mine has the place for the battery, but I haven't found a dummy to put in it yet.
I made up a pack with AA batteries a few years ago, along with the ARBE, and listened to it for several days. I had to use an antenna tunner becasue of a 3000 watt AM station less than 3 miles from my house.

Thanks for posting the paper work for the radio. The battery still in place along with the paperwork really makes this a unique find...
Thanks again...

Jonboy,
The link to your original instruction page is broken. I have been offered one of these. Can you send me a copy of yours.
Thanks in advance,
Dwayne

Thats the one, Jonboy. Those are really interesting. Sears customer service in 1925! I love finding original documents and letters like this with these old radios. Is that all there is to page 7? It seems to be cut off.

Thanks for taking the time to post this again.

Dwayne
