but what I need is the 1923. Specifically I need information on the model 4000 (the last model in my catalog is 2900).

Yes, that's how I knew the model number, but my set has a manufactured variometer assembly instead of the two separate parts in the magazine article. I'd like to find an ad for that assembly, and ideally plans that the builder followed. He changed some stuff as time went on, and I'd like to put it back to "original." In fact, as he eventually left it, the variable capacitor isn't even connected, and the circuit is fairly goofy.

This is the set, cleaned up from when I bought it:

If you can find it Sleeper's magazine should have it. A upgraded version of the Radio and Modeling Engineering 4000 would be in a later issue.

I have the magazines, but it's not there. It might be in one of his 1923 books (he seemed to have a new one every month or so) but I haven't found it.

The original article showed two ordinary variometers side by side. This unit has the two on one form, and that pair of small windings on the left are in series with the right-hand stator (left and right as viewed in the photo, from the back of the set). It uses brass castings and can't possibly be homemade.

I also have an ad in the "classified" section for a WD11 tube socket. There's a 99 socket in it now, but that was not even screwed down to the baseboard, and the Paragon rheostat is much too low in resistance to control a 99. As the set is now, the variable capacitor (by the O.C. White Co., Worcester, still in business making lamp fixtures) is not connected, and neither is the tap switch. The capacitor has adjustable plate spacing and can be made to reach 50pF or more. It was advertised in QST in late 1922.

The builder also paid good money for a manufactured oak cabinet.

I'm quite sure it's a Sleeper. The dials are Sleeper (General Apparatus) parts and it's the only set I've seen with two variometers and a vernier condenser.

It has had other changes. I'm pretty sure the mica capacitors were added, and the two in parallel are now in series with the grid leak which makes no sense at all. The grid capacitor is a Muter, and as far as I can find out, Muter began in 1923 (but I haven't found any ads). The leak is an S.S. Kresge (five-and-dime stores). There are holes where an earlier leak and capacitor may have been.

It's an intriguing mystery, which is why I bought the set (in the ARF Classifieds a month ago).

alan,

its not in this 1923 construction booklet by sleeper

The 1922 Radio Hook ups by Sleeper has a similar circuit but it looks like two separate variometers also.

Thanks, I don't have the Hook-ups book. He did usually recycle already-in-print material for his books, so that is probably right out of Radio Engineering, page for page.

Thanks also; I don't have that book either, which would have been a logical place to check.

The Radio News set has a variocoupler, with a primary winding going to antenna and ground, and the usual tuning capacitor. It says you can use an external variometer for regeneration.

You may be aware of this, but Google Books lists several books by Sleeper. Unfortunately, not all of them are available for download. Once you click on a book, the ones that are available will show a "EBOOK-FREE" box in the upper left hand corner. If you mouse over the box it will give you an option to download the PDF or you can just view it in your browser. Radio Hookups is one of the available books.

Here's the link -

Thanks, I never thought of that.

Radio & Model Engineering in May 1923 advertised his book "Six Successful Radio Sets" and one of them is the 4000. Since "101 Receiving Circuits" was advertised simultaneously in June, one would expect the 4000 not to be included there:

If this ad is accurate, the 4000 is the same two-variometer design from the magazine:

unless there happened to be an ad for the parts in the back of the book.

Here is the "before" shot of the set. I was told it came from an antique shop in NW Iowa:

I also thought that "Six Successful Radio Sets" would be a good candidate, mostly because it was listed as published 1923. I searched for a downloadable or paper copy but was not successful. The only thing I came up with was this thread from 2009. The OP said he intended to copy it, so maybe you can contact him. His website still exists. Here's the thread -

Keep us informed of your results, it's an interesting radio.

I know there are many sites with downloadable books, but has anyone created a list of sites that would contain downloadable books, catalogues, etc for vintage radio useful to our hobby?

Alan, considering a WD11 socket might be hard to find, why not use a WD12 and a regular UV socket?

Unfortunately, has a 500 pF variable capacitor and a variocoupler along with the two variometers. I appreciate the suggestion though.

I wish I could use a WD12, as I have a period-correct socket that fits the mounting holes. But the WD12 has the standard UX pinout with grid and plate on adjacent pins, and I'd have to modify the bus bar. Which I could do, but at some point it stops being a 1923 homebrew and becomes a 2014 recreation.

do you have a 1923 coto-coil catalog.the variometer sure looks like
their product.

Fascinating idea. Only a 1924 though, and there's nothing like it in there:

Their coil forms seem to be fairly thick. Sleeper on the other hand offered a thin tubing made from wood pulp . The one I have does appear to be wood pulp, tar-impregnated, and brittle enough that two screw heads pulled through it. It's 3 3/4" diameter.

Well that one is a dual variometer on a single tube, but it plugs into a standard honeycomb mount and has wooden rotors.
