Power - Triode (over 1000V 100W) ·Triode
Massive water-cooled Tesla transmitting triode for very-high-power RF amplification. Approximately 150 kW plate dissipation, 20 kV capability, and very high anode current suit enormous low-frequency transmitter installations.
Water-cooled directly heated transmitting triode with 150 kW anode dissipation for high-frequency power amplification up to about 3 MHz.
General specifications
Properties common to every published source and operating point.
Electrical assignments shared by every tube using this base designation.
No verified pinout is recorded for this base designation.
1 physical section, each with unique specifications.
Section 1
Maximum anode voltage also has lower condition-specific limits for modulated/higher-frequency service; preserved in parameters/notes.
Source-dependent data
Each block preserves the test conditions and published values from one reference. Values from different sources are intentionally kept separate.
