Thanks to all for information about the hand crank telephone dynamotor:
- 80 to 100 volts
- about 20 cycles
- rings a bell or other device at the operators place
- will bite you if you are careless
- wil bring worms up from the ground
It’s nice to hear from folks who remember using them (even while standing on a chair to reach the thing!)
