![]() One word about the radio part of this item: the radio is a TRF (Tuned Radio-Frequency, as opposed to a Superheterodyne) receiver with only 4 tubes, one of the last TRF's ever built. Fortunately I did not have toĭo this to the clock of this radio, because it works fine and Generated by the cooling-down rotor case. Rotor by the only hole available to equalize the underpressure, You'll see the oil disappearing immediately, sucked inside the Position it with the pinion up, and drop oil, drop by drop, on that It pinion up into an oven preheated to 125☏ for 15 minutes, take it out, Is working perfectly in all cases I applied it: remove the rotor, put I forgot where I read this recipee, which People attempt to lubricate the gear inside by trying to open the case of an "H" rotor, and it canīe seen, that there is only one hole, for the output pinion. Ref.3 above shows pictures of rotors, i.a. Often Telechron clockworks stop working because of missing lubrication. PleaseĮ-mail me (Kris) for any questions, ich spreche Deutsch, je parle Français. It works with a sensitivity, selectivity and volume that is amazing for a 4-tube TRF. The radio comes with its original cardboard back plane (pict.s 4,6), its original paper sticker (pict.10), and with all 4 original General Electric tubes. The radio has one little blemish, its right clock control knob is not original, but from its cousin, the GE 50, also for sale (pict.12), I am trying to get one. The cabinet design was also used by Telechron for the 8H61 "Switch Alarm" clock. The 8H59 and 8H67 Musalarm were the first alarm clock radios and due to a shortage of alarm clocks in general so shortly after the war, sold like hotcakes (see pict.23). in a very rare and collectible mottled UREA cabinet (see ref.5). The first is the Collura radio alarm clock, the second probably was designed by Collura too, and was made i.a. Two of the novelty clocks were radio alarm clocks (Musalarm), the 8H59 and the 8H67. The 8 Series was for novelty clocks, timers and radios, odd-numbered models were Telechrons, even-numbered were GE. Starting in 1932, Telechron and GE began giving initial model numbers to their clocks to match their function. General Electric acquired 50% of Telechron sometime in the 1930's, but took over the prospering company completely shortly after the war, ran it into the ground over a period of several decades, and then sold what was left to Timex. It was Henry Ellis Warren, who in 1908 started to develop what is today known as a Telechron clock (see ref.3 below). "Clock radio" is understood here as a device combining an alarm clock to a radio with the purpose of waking up, not just a radio and a clock sharing the same cabinet, or a radio switched on by a clock to warm up in time. His patent with number 145'996 "Design for a Combination Radio Receiver and Timer Clockcase" was submitted on Jan.21, 1946 and granted on Dec.3, 1946 (ref.2 and pict.s 19,20). I claim the first radio alarm clock was invented by Francesco Collura (representing Telechron), and it is exactly this Telechron 8H59. That's the power of Wikipedia - and its danger. When you try to find who these two gentlemen were, you are by your own. Reynolds, in the 1940s and another design was also invented by Paul L. The 32 answers with Reynolds all show the same sentence: "The first radio alarm clock was invented by James F. When you google "first radio alarm clock" you get 54 answers, when you forbid "Reynolds" in the search you get 32 answers less, the remaining ones having nothing to do with history, but with birthday presents. It's a Telechron Musalarm radio alarm clock - it is the first alarm clock radio ever made, and possibly the last TRF radio ever made Telechron 8H59 Musalarm, a 1946 4-tube TRF Radio Alarm Clock and the First ever made Alarm Clock Radio, Serviced and Perfectly Working from General Electric Co.1946 Telechron GE Musalarm 8H59, First Radio Alarm Clock ![]() In French: TSF for Télégraphie sans fil.Īll listed radios etc. Here you find 2858 models, 2080 with images and 1998 with schematics for wireless sets etc. See "Data change" for further contributors.

The following models use the same schematic and cabinet but have different cabinet colors: Model Number Cabinet color is Antique White and Mahogany.
