My 1948 Dodge has a Motorola 8 tube radio with push pull 6V6's (the octal base version of a 765). I've owned the car now for 60 years. In the 60's I could drive across country overnight and listen to the same AM station for 500 miles. Those were fantastic receivers even if they were power hungry mine pulls 9.5 amps at 6 volts. It's good to see your EICO 249 VTVM complete with the Uniprobe. I have the 249 that my Father built in 1958 and use it often on my bench. I t still has it's Uniprobe. I'm glad I came across your channel and will look forward to seeing part 2. Thanks for posting...
Those old radios resemble military gear in the way they're built. Tons of noise suppression, transformers sealed in metal cans, all kinds of bypass capacitors that you would never find in a home set. And all of them have an RF amplifier in the front end. Those old engineers were pretty clever guys.
This reminds me of the time spent in my "cave" trying to fix radios. My power supply was a 12 volt 6 cell battery with the connectors protruding from cell to cell. My battery charger was a selenium rectifier with a light bulb in series... Fun times
The Philco made 4635 radio was very well designed and the schematic Philco published is very well detailed for isolating problems in the circuitry. These car radios are more difficult to restore than most home based radios of this vintage that were kept indoors. Be optimistic Vern. I know you can get it working again. Steve from Chicago,IL
Audio sounds good. At 22:20, that's true of printers and copiers by design, (and law), since the government does not want you printing money! Although one can always override that.
As of late, ive veen trying to find someone with plastic printing capabilities to replicate the ww2 era volksempfanger radios cabinet, which was originally bakelite...the backing is perforated particle board, and inside is a blue tooth speaker readily connectable to your cellphone for instant period correct music .....absolutely nobody is interested in helping me achieve this....im posting it here in hopes someone also thinks its a good idea and would like to help, as similar minds.....thanks
