In a Nutshell
The cult radio in rare mahogany burl, fully restored, working and in mint condition

Introduction:
I consider the 1929 microsynchronous radio series by the Victor Talking Machine Co. as one of the brightest milestones in radio technology and radio history. I share this opinion with the myriads of customers who despite the upcoming depression bought one of these radios. Sales in 1929 totalled more than 50 million dollars for about 300'000 units, the largest in the company's history. The new micro-synch owners, even after 5 or 10 years, lauded the outstanding reception and selectivity and the ease of use of their tuners, the exceptional reproduction quality and volume reserve of the 245 amplifiers, and the surprisingly clean bass of their huge Burtex coned electrodynamic speakers. The Electrola with its brushless induction disc motor (no belt, no rubber, no failure) was way ahead of its time as was its low impedance magnetic pick-up.
A detailed historical and technical documentation, summarizing my own research into, and experience with this radio, could be found in my eBay auctions for Items 6573834006 of Nov.6, 2005 and 270042331293 of Oct.22, 2006, the latter having been copied to here (ref.1). Since many years the 3 separate parts of the radio, tuner, amplifier and speaker, sell like hot cakes especially to the Asian market. The most obvious reason may be the fact that the cabinets are often in unrestorable condition, and the guts are more easy to ship and so sexy that they can very well exist and work without a cabinet (pict.24). Especially the 245 amplifier is highly sought-after by guitar afficionados, because of its transformer coupled stages and the powerful 2x45 15 Watt push-pull audio output. Unfortunately most amplifiers turn out to be defect, the sellers having no clue how to test them (see below) without having the whole radio.
Here I offer the top model RE-45 of the 1929 series in rare mahogany burl finish (walnut was the other option), made in Canada and looking and working like new. The series also included models R-32 (simple lowboy console) and R-52 (highboy console with doors) (pict.78).

About my Radiogram:

The radio was part of a large collection, the last and most valuable exemplars of which only recently came to auction here in Vancouver. Have a look at more late 1920's gems coming up. The radios were never restored before, but fortunately none of them ever saw a barn or an attic, that are the primary causes of death for these beauties. The 245 amplifier has 17 magnetic coils, the speaker another two and the pickup one more (pict.60, the schematics in pict.s 45, 46, 60 have been drawn from the actual radio, and the values for the Ohmic resistances of all coils are averages over many radios I had restored before). The probability that at least one of these 20 coils has an open winding (mostly caused by copper oxydation at spots exposed to air, not by overdriven voltages or currents) is extremely high. That makes it necessary to sacrifice other defect spare components and use them as donors for parts. The amplifier's transformer cans are filled with black tar, and are a mess to refurbish. But it can be and must be done. The amplifier has been painstakingly cleaned and repainted with High-Heat Ultra Rust-Oleum paint. The Electrola pickup in all cases has to be rebuilt, because two rubber parts have deteriorated and must be replaced. In most cases also the pickup coil is open and has to be rewound, as described in the documentation about my Victrola VE7-26X. The pickup of this RE-45 Electrola has its original coil with about 80 Ohm DC resistance. The tuner has been aligned and neutralized as described in literature (ref.4). Both, the radio and the Electrola work flawlessly, as you can see from a youtube video (ref.5 or click on thumbnail 80). Please e-mail me (Kris) for any questions, ich spreche Deutsch, je parle Français.
