No eye tube in sight (pun). It does, however, provide some minimal information on the 1629 and a little more information on the 6E5. Apparently, the 1629 is a military/industrial tube. The 1629 speces: Tube outline diagram 13H Tube terminal diagram 7AL Heater voltage 12.6 Heater current 0.15 A pin 1 NC pin 2 H (one end of the heater) pin 3 PT/RCJ (apparently this means ray control grid) pin 4 TA (fluorescent target) pin 5 GT (not sure what this is, some extra gird??) pin 6 -- (they left this blank) pin 7 H (other end of heater) pin 8 K (cathode) I'd imagine the voltages necessary are similar to the 6E5. The book makes no mention of what to use.
