There is no guarantee of the accuracy of any information offered. Point-to-Point Radio Satellite Communications Wireless Infrastructure Go to. The data and files offered here are from vintage sources that are no longer published. I stock over 500,000 schematics for hundreds of manufacturers.Įach radio schematic is digitized individually and checked to provide the clearest diagram possible from the original printing. Once researchers design a new circuit, then they use CRO to. The files offered here are digitized in high resolution from the original factory service documents. It is used in laboratories for the purpose of research. GE Factory Schematics - Models/Chassis Available:įor GE Service Manuals see the GE Service Manual section.įor more GE schematics see the Basic Schematics section. Literature/Schematics (1) Antique Radio Magazine n.49, June 2002, page 42 (Ita/Eng). A single tuned circuit, but lots if gain, and since there was AGC, automatic gin control, the illusion of. Just a few weeks after Regency (IDEA) has launched the first transistor radio, Regency TR-1 with 4 transistors, Raytheon brought its much bigger 8TP with the models 8TP-1 (tan leather), 8TP-2 (brown leather), 8TP-3 (beige. Making A Transistor Radio, 2nd edition cover. «TR-610 is the one by which all others are judged.» Metal golden grille sales 436,952 items. Portable set > 8 inch (also usable without mains) Dimensions (WHD) 9.25 x 7 x 2.75 inch / 235 x 178 x 70 mm. The PNP-NPN transistor combination is configured as a non-inverting amplifier, featuring feedback from the output to the input through a 10uF capacitor and a 2k2 resistor. The TR-610 is the most representative of all early transistor radios. Other Models Here you find 1 models, 1 with images and 1 with schematics for wireless sets etc. See 'Data change' for further contributors. General Electric Factory Schematics 1946 -1961 This simple two transistor oscillator circuit serves as an excellent supplementary continuous lamp flasher for your current flashlight setup. Transistor Radios 1954-68 (p.77) Literature/Schematics (1) Collectors Guide To TrR1 Bunis trans.94 (1996, page 276) Author Model page created by Günther Stabe 19.8.20. It normally takes up to 24 hours to receive the download instructions via email but please allow 1 - 2 business days. If you still can't find your model or chassis contact me for availability. If your model or chassis is not listed below, full GE radio service manuals can be found for most 1930 through 1950s GE models here.įor basic schematics for General Electric models not listed below you can also check the Basic Schematics section. They are scanned in high resolution directly from the original GE Factory Radio Service Guides. These files contain the schematic and parts list published by General Electric for service technicians. I’ve redrawn the original schematic in EasyEDA for my study, available here. Regenerative Receivers - techlib A Short Wave Regenerative Receiver Project - tuberadio A Simple Regen Radio for Beginners - QST September 2000, pp 61-64 Circuit. These are General Electric (U.S.A) schematics with parts lists for GE radio models manufactured in the U.S. The early transistor radios had six transistors, consisting of the mixer/oscillator transistor at the antenna, two transistors amplifying the 455 KC. In this circuit, the regen control comprises Q1 and it’s biasing components. While testing the above circuit we have observed that this circuit works best between 3.3 to 3.5 Volt range. The factory service manuals with schematics and diagrams listed by manufacturer at. However, the schematics can often be enough to help in fault finding. But like the previous circuit, this circuit uses two 2N3904 general-purpose transistors to generate the resonance frequency. Welcome to '' Here you will find factory service manuals, schematics, and diagrams for thousands of antique tube and vintage transistor radios, auto radios, record players and record changers, tube amplifiers, tape recorders, and more. Some of the radio manuals listed are only circuit diagrams. General Electric Factory Schematics 1946 - 1965 Next, this is another FM radio receiver circuit that has a two-transistor configuration.
