1922 Atwater Kent Model 2 Breadboard Radio * Factory Built * Excellent Cond. For SaleIf you collect antique radios, make sure to check out all of my sales this week. I've assembled some excellent items that seldom surface on .Here's a rare, factory-built Atwater Kent Model 3945 breadboard radio, also known as the Model 2. The radio -- very scarce, even by Atwater Kent standards -- was manufactured in 1922 and comprises an Atwater Kent Coupled Circuit Tuner (far left component on board), an Atwater Kent Mounted Variometer (center component), and an Atwater Kent detector/amplifier island (far right component on the board). Included with the radio are 3 good brass base, tipped UV-201 tubes. These 1 amp tubes are correct for the radio, and they're also some of the most beautiful tubes ever manufactured, with an elaborate plate structure and tinted glass envelopes.Condition of the radio is excellent throughout, and the radio is an authentic, factory-built Model 2, not a kit or a replica. The paint on the TA island is original and in excellent condition, particularly for AK green paint, which had a tendency to rust. There's some oxidation on the TA's mounting flange, but much less than most you see. The x-shaped factory wiring connection on the underside of the board is original and correct. The early Coupled Circuit tuner with a duct in the bakelite case through which the connecting wire can be threaded from beneath the board is also correct (this hole can be found only in Coupled Circuit tuners that were intended for use on factory-built breadboard radios).
Bakelite on all parts is in excellent condition, with a nice glossy surface and no cracks or other damage. The dials are beautiful, with clear original markings and no chips or nicks. The backing plates are beautiful, with no chips or hairline fractures. The potted AK transformers, the binding posts and binding post hardware on the TA are all original and are all in excellent condition. There's tarnish on the brass parts, but no corrosion or damage.
The board and board finish are original and in excellent condition. No warp in the board, no bad gapping on the end caps. The four rubber feet on the underside of the board are probably replacements -- the originals would have been tacked closer to the corners. An earlier owner's ID number is scratched lightly into the wood just in front of the TA island, but the mark is tiny and you have to look for it to find it. To some extent I'm splitting hairs here. While the radio is not without flaw, it is nonetheless an exceptionally nice example of an exceptionally scarce set. If you're waiting around for someone to offer you an authentic AK Model 2 breadboard that's in mint condition, you're going to be six feet underground before you find it.
Because Atwater Kent didn't have a license to manufacture regenerative radios, the variometer on these factory-made sets was shipped to the purchaser as a separate unit, with simple mounting and wiring instructions. By installing the variometer in the large, empty space between the tuner and the TA island, the purchaser could then integrate the variometer into the radio's circuit and convert the receiver into a regenerative one, evading the licensing restrictions that prohibited AK from manufacturing regnerative sets at their factory.
And because the radio was manufactured before the summer of 1923, it does not have a tag, which is correct for an authentic Model 2. If you've been offered a Model 2 or other pre-Model 5 breadboard with tags on it, you've probably been offered a fake.
As noted above, the radio works. The second stage transformer has an open winding, but the first stage transformer has sufficient amplification to power either a headset or a very sensitive horn speaker. Please note that this is an early regenerative battery radio: you don't simply plug it into a wall outlet as you would a later AC radio. If you want to operate the radio, you'll need a good regulated DC power supply (I'd recommend an ARBEIII), a longwire outdoor antenna (at least 100 feet long and 20 feet off the ground) a good indoor ground connection and a pair of 1920's headphones or a sensitive horn speaker. It will also help to have had some experience tuning and operating an early battery radio. They're somewhat complicated to use, and it takes some patience to learn the ropes. The tubes included with it have only modest emissions, but they're still sufficient to tune properly and power the output section.
That's about it.
