[BC] 25 Hz AC in New Orleans

"Ron Cole" asked:<rondcole at gmail.com>
"For the old-timers here... were any vintage radio transmitters
(Gates, RCA, etc.) certified to run on 25 Hz AC power?"

The transmitter we got from the back room at WASH when we built WHFS 
102.3 had a 25 Hz power supply.  The story was that it had been used in 
propagation tests in the 25 Hz part of upper New York state. The story 
continued that it was given / lent by Armstrong to Ev Dillard to get 
WASH on the air from their then-new Wheaton, MD, site.  Of course I 
built a 60 Hz replacement. The 25 Hz supply is still weighing down a 
corner of my garage!  and I do mean weighing down.....
