Near Mint, Working 1924 Grebe Mu-2 Dry Cell Radio W/batt. Box & Great Provenance For Sale


Please note: if you're traveling or on vacation and would like me to delay shipping until you return, I'll be happy to store it for up 6 weeks. I only ask that you settle up payment immediately after the listing closes.Here's a gorgeous, working Grebe MU-2 Synchrophase radio, the only dry cell Synchrophase set Grebe ever made, and a radio that was manufactured only briefly at the beginning of the 1st Synchrophase production run. The radio was sold with a factory-built cabinet/pedestal in which to house its batteries, and its rheostats were designed to accomodate the current and voltage of UX-99 tubes rather 01A's. You'll probably see a hundred or more MU-1 radios before you'll see a single MU-2, so I think it's fair to say that the MU-2 is a special set.This particular MU-2 is even more special than the others. The radio, battery box and paperwork were formerly on permanent display at the Indiana Historic Museum in Ligonier IN, where they were the centerpiece of that fabulous collection and the pride and joy of the museum's well-known curator Fred Schultz. Condition is excellent, as you can see in the photographs. The faux-mahogany bakelite panel is nearly perfect (it actually looks like mahogany, maybe even better), and the gold-plated escutcheons still gleam. The finish on both the radio and the battery box is original, with only minor scattered marks consistent with age, authenticity, and gentle handling. The chassis is spotless, and the green binocular coils are almost like new. The audio transformers are original and both of them are good. The wiring is pristine, and there is no rust or other damage anywhere. The interior yellow serial number card is complete, undamaged and legible throughout. The battery hook-up sheet was removed from the underside of the base (probably when the radio was originally set-up by the dealer), but I'll include a battery wiring diagram with it, so that the radio can be easily used an ARBEIII or other regulated DC power supply. There are no acid stains inside the battery cabinet, nor are there any chips or cracks.Look at the photos. They should tell the story better than I do. The 2nd photograph shows the paperwork that's included with the radio. Only the manual is a reproduction. Everything else is original, including the scarce 1924 brochure announcing the Synchrophase's introduction.As noted above, the radio still works. Quite well, actually. If you'd like to operate it, you'll need a good regulated power supply (I'd recommend an ARBE III), a good indoor ground connection, a longwire outdoor antenna (ham radio type -- about 120 feet long and 20 feet off of the ground), and a 1920's horn loudspeaker. The earliest Synchrophase sets, such as this one, were designed to be used with horn speakers rather than cones, but they will actually work with either. If used with a cone, the cone must be reasonably sensitive one, capable of being powered with 90v B+ or less.The radio measures approximately 22" wide by 14" deep by 9" high. Shipping weight, properly packed, will be about 45 lb. The battery cabinet measures approximately 25" wide by 15" deep by 5" high. Shipping weight, properly packed, will be about 18 lb. That's about it. I will package the radio and battery cabinet properly so that they arrive at your doorstep safely. I have been shipping antique phonographs and radios for years, and if you check my response, you'll see that I know how to do it correctly. OVERSEAS BUYERS PLEASE NOTE: This radio is large and heavy, and because the battery box must be shipped in a separate package, shipping costs are going to be quite high. Therefore, if you're offerding from outside the US, please contact me first for a shipping quote so that I confirm my ability to get everything to you. Buyer prepays and includes shipping. Overseas customers may remit payment with Paypal only. sale participants with no prior response should contact me prior to placing a offer. Thanks.
