1922 Amrad 3500-1 Regenerative "double Decker" Radio * Near Mint & Working For SaleMake sure to check out all of my sales after you've looked at this one. I'm listing an eclectic assortment of hard-to-find technological, musical and mechanical antiques, and I suspect there will be something of interest to almost everyone. Here's a 1922 AMRAD 3500-1 Broadcast Receiver. This iconic "double-decker" regenerative radio is complete, original and in near mint condition throughout. Both of the original AMRAD audio transformers are good, as is the proprietary AMRAD 3257 Radioformer, a plug-in RF transformer (on the back of the tuner) that is required in order to operate the radio, but which is missing from many if not most examples of this radio. The radio comes with a complete set of good brass base tipped, tipped 01A tubes, and it will be ready to play or display as soon as it arrives.As you can see in the photos, the radio is a gem. The cabinet finish is original, with virtually no wear, just a few minor, scattered marks consistent with age and gentle handling. The wafer-thin brushed bakelite panel is just about flawless. No chips, no cracks, no blemishes, no filled holes, no repairs or distress of any type. The engraved panel lettering is original, and it's still bright and crisp. The dials are likewise almost like new. All of the tiny knurled panel nuts are still in place, and the panel tags are original and perfect. All four original cabinet feet are still in place on the underside of the tuner. All of the binding post nuts are original, and all are present, with the original color coding scheme still intact on the battery posts. One of the two short flat sheet metal connectors on the back of the radio -- linking the second set of sec. posts -- is missing, but all of the other connecting strips are original and present on the radio. When operating the radio, I've used a small piece of wire to connect those two posts.Both chassis are nearly perfect. Wiring is clean and straight and original throughout. "Wicker basket" tuners are beautiful and their color is still a vibrant blueberry. There is no rust evident on any of the small chassis hardware, nor even any significant tarnish. All four tube screens are present, and none of them are damaged or malformed. The soldered connections are all secure. The Radioformer socket on the rear interior of the tuner, in which the RF coil is seated, has a tiny chip missing on the end of the guide slot, so I've placed a bit of electrical tape around the base circumference of the RF coil to keep it secure in the socket and pressed snugly against the contacts. None of this is visible from any viewing angle, and of course you're welcome to remove the tape from the base of the coil if you'd like. I've just placed it there so the radio will operate without an issue.The radio has been tested as recently as this weekend, and it pulls in near and distant stations with selectivity and clarity. If you want to operate the set, you'll need a longwire outdoor antenna (ham radio type -- approximately 120 feet long and 20 feet off the ground), a good regulated DC power supply (I'd recommend and ARBEIII), a sensitive pair of 1920's headphones (or a loudspeaker) and a good indoor ground connection. The brass base tipped tubes have good emissions, and you should no trouble using them with the radio. If you're familiar tuning principles of an early 20's regenerative radio, and you have the proper antenna erected, and the proper DC power supply, you should be able to set up and use this radio shortly after it arrives. If you're not familiar with the tuning principles of an early 1920's radio, you're going to have your work cut out for you. The radio is very sensitive and very selective, but it requires a reasonably skilled operator at the controls in order to make it work. Please keep this in mind. As I said about the AMRAD 2575 crystal receiver I listed on last month: If you want the best, this is the best. You'll never have another chance...unless you can figure out a way to transport yourself back 90 years.
