10KP17 CRT: maximum anode/grid3 12000 V DC; grid2 +700 V or -180 V, grid1 negative bias -180 V and positive peak +2 V; grid1 drive from cutoff max 65 V. Heater-cathode ±150 V normally, exceptional 410 V heater-negative for <=15 s warm-up. Typical Va 9000 V, grid2 250 V, grid1 cutoff -27 to -63 V, focusing-coil current 105 mA. Grid1 circuit resistance max 1.5 MΩ. Near maximum positive grid1 bias limit anode input power to 6 W. P17 dual-persistence greenish/yellow metal-backed phosphor, magnetic focus/deflection ~50°. Cathode capacitance 5 pF, grid1 capacitance 6 pF.

Source-dependent data

Operating conditions by source

Each block preserves the test conditions and published values from one reference. Values from different sources are intentionally kept separate.

No source-specific operating conditions are recorded.
