Zenith 5R312 voltages
#10

Arran:
Can you expand more on this 25 cycle thing..My schematic says line voltage 115V. What was the standard in the late 30's? 60 or 25? and whats the difference and why? Parts list says they sold power transformers in 50-60 cycle and 25 cycle. Would this cause the B+ to be higher?
Also expand on this bucking transformer if you can. I dont have much room in chassis.
thanks Buzz
