I don't know about the 1600 volt supply for the

used to drive some printer and punch coils in the early systems?

Here are a few links, I found ....
Univac I - "130 tubes (2050 thyratrons), when fired, drove the hammers to print the
characters in the
blockette of tape data. "

"Where I came from, Thyratrons were gas-filled (Argon,
if I recall correctly), and the mercury ones were called Ignitrons,
although that may have only been GE's trade-name for them.
A line-printer I used to have (from the Univac SS-90) used
thyratrons for the hammer drivers. I still have a 6-volt
battery-charger with an ignitron."
