[ARC5] Vibrator Power Supplies

[Michael Hanz]

Thus the need for "Receivers, Ash" found in abundance around the 
aircraft in the era...

It's an interesting study in itself - 
http://aafradio.org/flightdeck/Peripherals-misc.html has more on the 
WWII aircraft ash trays, but I have a 1936 Ford ash tray that was 
incorporated into a later 5.75" Dzus mounted rack mount format for 
postwar aircraft, and I seem to recall photos of ash trays in the B-52, 
though I think they were not drawn from automobile manufacturer's 
products as during the war.
