This is a General Electric Radio H-634 . All the tubes appear to be in place .T is a lot of accumulated dust on the inside of the cabinet. The 110vac cord is very brittle and bare in several spots , so I did not try the radio out . The case itself is in very good condition with only minor scratches . On the speaker cloth t is a short thread pulled out in one spot .On the lower plastic ivory colored piece t is a crack,however the piece is intact. Shipping weight will be 20 lbs.Thanks for looking! General Electric Model H-634 AC/DC operation: 1939 This receiver shows several evolutionary improvements: Metal cased tubes for reliability, direct operation from AC line power without a transformer, a maximum of 8 pins in the tube base for connections and a standardized socket, and construction that eliminated the need for the mechanically vulnerable grid cap (the little metal post protruding from the top of the tube) on older receiver tubes. Equipped with pushbutton tuning, a superior speaker and two shortwave bands, it was considered a "quality" receiver. The set contained a loop antenna, but also had provision for connection to an outside antenna. The filaments of the tubes were connected in series with a voltage dropping resistor (or "ballast tube") included in the string to permit operation from 120 volt AC line voltage. This created a service problem: If one tube burns out, it is all tubes must be tested until the defective tube is located. Tube lineup: 6SA7 mixer, 6J5 IF oscillator, 6SK7 IF amplifier, 6SQ7 second detector and first audio amplifier, 25L6 speaker amplifier and 25Z6 dual rectifier. (With this nomenclature for tubes, the leading numerals indicate the filament voltage required.)
