Yo -
I have a data sheet, apparently a typed copy of an RCA
8-1/2" x 11" data sheet, on the 4AP10 Skiatron (dark-trace)
radar version. The dirt is as follows:
Heater 6.3 V _at_ 0.6 A
Mag focus and 40-degree mag deflection
Length 14-1/4" overall
Anode voltage 9900 max., 8000 min., 9000 typical
G2 voltage 500 max, 250 min., 300 typical
G1 0 V to -125 V; cutoff to 2 microamps occurs at -45 V
Heater-cathode voltage 125 V max
Pinout per EIA is 5AN:
H - 2 & 8
K - 7
G1 - 5
G2 - 3
Anode - Cap
The electron gun is reportedly capable of an unusually fine spot.
