I have done several simple radio restorations and have little knowledge about circuitry. I picked up the referenced 6 volt Monkey Wards circa 1936 farm radio radio recently and am completely stumped about the Rider schematic as shown. I have read a bit about the farm radios and how they use vibrators to simulate AC current so that a transformer can be used to adjust the voltage. I have also read a number of articles about building a battery eliminator to bypass the vibrator and power the radio. So here are my questions:
-1- The schematic doesn't give voltages on the tube pins, but I assume all the "A" heater voltage on the tubes is 6 volts; however when it comes to the "B" voltage I am lost. It appears that the oscillator and IF amp tubes use 90 volts, but can't figure out the other three tubes. I also see 135 and 145 volt power in places.
-2- Will it be possible to build a battery eliminator for this radio? If so I obviously need help so any suggestions will be appreciated.
-3- The other thing that confuses me is that I don't see a rectifier anywhere? Is this because the vibrator only creates a pseudo AC power that can be processed by the transformer but is still actually DC power?
