Production year 1924 The Crosley Super Trirdyn Regular first appeared in 1924. An issue of the Crosley Radio Weekly dated October 12, 1925 lists this radio for sale at a price of $45.00 without any accessories, which was a $5.00 drop in the regular price. The caption next to the radio reads as follows.... COAST TO COAST RADIO AT A VERY LOW PRICE "Sell the Super Trirdyn Regular for $45.00" That was the message dispatched last week by Powel Crosley, Jr., to his authorized dealers. The effect was instantaneous. Congratulations and messages of thanks poured in. Dealers appreciated the added opportunity of a more rapid turn-over. Consumers appreciated the savings. The Super Trirdyn Regular is exactly the same as the the Super Trirdyn Special except it is installed in a slightly smaller cabinet. It is a coast to coast receiver, in which the three tubes do the work of five or six. Lowering of the price will result in an increased demand for this radio, and dealers must be prepared to meet the requirements of their customers. Place an order immediately with your distributor - order at least half a dozen Super Trirdyn Regular radios. The Crosley Super Trirdyn Regular is a broadcast band only receiver that uses a total of three number 201 tubes. The receiver requires a set of headphones or a loud speaker such as the Crosley Musicone for operation. As was the case with a number of radios from this era, the power source was not AC, but rather DC. The Crosley Super Trirdyn Regular is powered by batteries that are difficult and expensive to come by today. One way to get around this problem would be to string a number of batteries in series. For example, say you needed a battery with 90 volts. Simply take around ten 9 volt batteries and run them in series. The output voltage would be 90 volts, but the ah(amp hours) or capacity stays the same. In other words, the string of batteries will run down quickly. The Crosley company claims that it is a special combination of their circuit that allows their radios to run from 3 tubes instead of six. The company explains the circuit as having a stage for tuned RF(radio frequency) amplification, another part of the circuit for Armstrong regeneration and a third used for reflexed amplification. Reflex amplification simply means that one or more tubes are used for both RF amplification and audio amplification. The size of the radio is 17-1/2" wide, by 71/2" high, by 7" deep. All of the photographs on this page show the radio in the condition it was received. I will post pictures of the restoration process and the completed radio once work begins on this receiver. |
