![]() Motorola 56X11 (1947) THIS RADIO HAS BEEN SOLD Brown plastic AM only radio. NEXT TIME I NEED ADVICE, I WILL TALK TO A PROFESSIONAL. Motorola radios sold To see more of this seller's radios, visit Jim Wassell's Attic. If you'd like additional pics please let me know. Its been tuned and aligned with new capacitors and new power cord added and resistors checked. :WHAT DO YOU MEAN, IM NOT SHOUTING, YOU ARE. THIS RADIO HAS BEEN SOLD Not unlike its cousin (51X12) this beautifully swirled dark walnut Bakelite Motorola is Mint with minimal wear A 10+ It plays really good. AFTER IT RUNS FOR AWHILE IT'S OK AND EVENS OUT.WHAT HAS TO BE DONE TO CORRECT THIS. The 56X11 was 'manufactured exclusively for sale to members of the US Armed Forces' and this one has been painted in Air. THE RADIO GOES ON ALMOST INSTANTLY, BUT THAN THE VOLUME GOES LOWER AND THEN HIGHER. :::I HAVE A 1939 MOTOROLA RADIO, AND IT PLAYS GREAT. On those units, it is possible to be ripping off 125+ WPM. With time, one can be a real speed demon, with the slowing factor only being the response time of the typebox if using an interconnected hard copy being made out on a teletype printer display.īUT when using the last device mentioned, as well as by just engaging the tape perforator( or newer units use memory discs ) There is no transitional upper/to/ lower case shifting, and a person who gets his start on one of those is not encumbered with those additional time consuming considerations. It's kinda like "find out what all is working, and then what isn't working is the problem" (Sherlock Holmes, I apoligize)Īnd then.there might also be this possibility.ever typed on a teletype or cipher machine? After that, you have a very small part of the radio to fix. As said above, the AVC will tell you if the RF part is working, the B+ will eliminate the power supply, then you have the RF and IF stages to worry about. Old mid 50s motorola table radio 8:46:58 AM Jesse Hancock (59993:0) Hi everyone, I have been working on a mid 50s motorola radio with a circuit board instead of a metal chassis. ![]() Measure the B+, the AVC, and the plate Voltage of the output stage, and insead of looking at a whole radio, look for the part of the radio that is causing the trouble. The radio has three seperate sections: the power supply, the RF and the Audio. Using any other meter on the AVC circuit will cause it to perform improperly, and voltages you see may not tell you much (though a normal 20,000 ohms per volt meter will tell you a bit about the AVC circuit-whether it's performing at all or not.results just won't be accurate, and the RF circuitry might overload with strong signals). Check to see if B voltages change, or AVC, though properly monitoring AVC requires a very high impedance meter, like a digital meter or a vacuum tube volt meter. Anybody with any ideas to locate a schematic wouild be appreciated.:Monitor voltages during the performance changes you note. :I have searched through the schematics but as i have no model number it is difficult, maybe no us equivalent was made. :Th valve lineup is 6K8GT,6K7GT,6K7GT,6Q7GT,6V6GT, Rectifier and Vibrator pack, it has capacitor tuning. :Hi i have an old car radio built in the uk by world radios ltd london under licence from motorola. When I removed the capacitor the radio played great.What's the purpose of this capacitor The radio works well without it. I thought mica capacitors were supposed to last forever. Both used a non-synchronous vibrator with either 0Z4 or 6X5 rectifier. Shouldn't this read megohms on an ohmeter The other end of this capacitor went to B-, the circuit common. Both were also made with either Loktal or Octal valves. Both use a 6A8 valve instead of the 6K8, and a 6K6 instead of the 6V6. I did find two 1939 models that are close. ![]() equivalent for your Motorola licensed World Radios Ltd.radio valve line-up.
