[ARC5] Vibrator Power Supplies

[Robert Eleazer]

I have a 1945 Aviation Magazine that has a full page color ad touting a new innovation: vibrator power supplies.

Also note that the lower iron in higher frequency transformers affects what voltage the transformer can handle at lower frequencies.  Lower frequencies, then lower voltage is allowed.  I am using those transformers at what I assume is 1/2 their normal operating voltage in their secondaries: 125VAC rather than the 250V I assume was the norm. 

And they are big heavy beasts.
