[NJARC] Tube info?

[Al Klase]

Everyone needs a copy of Lud Sibley's "Tube Lore"

"Besides the usual three-digit numbering, WE assigned "D-specification" 
numbers to special tubes:  Preliminary-production types, modified or 
selected versions, low-usage types, etc."

"D-86326  Receiving triode, high-insulation 101D, discontinued after 
improved production of 101D.  (Used) in line amps of C2 carrier 
telephone system."

If Gerry Tyne, "Saga of the Vacuum Tube," is right, this was 1921-ish.
