[ARC5] Vibrator Power Supplies

[George Babits]

Actually though, they will work.  When I was a novice in 1957, I had a low 
power transmitter with a vibrator supply designed to run off a 6 volt wet 
cell.  My elmer wound a 6 volt transformer with heavy wire and we ran that 
into the vibrator transformer.  My signal may have been horriblee, but I 
worked ll over the country with that transmitter.   I also recall him saying 
that they used to do that with car radios too.
