[ARC5] [Milsurplus] "1917"

[Rich Post]

Yes, the BC-14A  (SCR-54A) manual mentioned a certain possible accessory, a
DT-3A with these curious connections marked "Tickler Coil Terminals".  It
used a VT-1.   (see page 15 of manual)
Here's a link to the manual and lots of others of that era.

The Major was still a Captain at the time and working on something that
would later be called a superheterodyne.
The Wien quenched spark used a series of circular plates for small gaps of
0.2 MM each and about 1200 volts each for a tonal signature called the
"whistling' arc.  It also made less poise locally.
