General Electric Model 103 (RadioMuseum.org) - RF Cafe

General Electric Model 103 - RadioMuseum.org

It has been a while since posting on of these Radio Data Sheet 333 that often appeared in vintage electronics magazines like Radio-Craft. This one is for General Electric Radio Models 100, 101, 103 and 105. The RadioMuseum.org website has a very nicely restored General Electric Model 103 radio. Per their description: "The General Electric 103 is an AC/DC operated 5 tube BC band receiver. The BC band frequency tuning range is 540-1600 kHz. Has built-in loop antenna with provisions for connecting an external antenna. The following models use the same schematic and chassis but have different cabinets..." A few Model 100 versions show up on eBay in case you might be interested in acquiring one.

Radio Data Sheet 333 General Electric Models 100, 101, 103 and 105, March 1946 Radio-Craft - RF Cafe

Electrical Rating (Input)

Voltage ...... 105-125 volts a.c. or d.c,

Frequency on a.c. ...... 25 to 60 cycles

Wattage ...... 40 watts

Operating Frequencies

Broadcast Band ...... 540-1600 kilocycles

I.f. Amplifier ...... 455 kilocycles

Procedure - General

 1. Turn dial scale pointer as far counter-clockwise as possible. The pointer should coincide with the first marking at the left of the scale. If it doesn't, remove chassis and slip pointer on shaft until the pointer is under reference mark when chassis is bolted in place.

2. For i.f. and r.f. alignments, the output meter is connected across the loudspeaker voice coil terminals.

3. Keep radio volume control at maximum and attenuate test oscillator signal output so that the output meter reading never exceeds 1-1/4 volts.

4. The chassis must be removed from the cabinet during i.f. alignment. For r.f. alignment bolt the chassis in the cabinet securely, the r.f. and osc. trimmers are then available through the hole in the Beam−a−scope assembly when the back cover is removed.

5. Connect the capacitor as listed in column 2, between the output "High Side" of test oscillator and the point of . input specified.

Radio Service Data Sheets

These schematics, tuning instructions, and other data are reproduced from my collection of vintage radio and electronics magazines. As back in the era, similar schematic and service info was available for purchase from sources such as SAMS Photofacts, but these printings were a no-cost bonus for readers. There are 227 Radio Service Data Sheets as of December 28, 2020.

RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The World Wide Web (Internet) was largely an unknown entity at the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps while tying up your telephone line, and a nice lady's voice announced "You've Got Mail" when a new message arrived...
