D14-120GH is a tube type in the TubeDatabase archive (class: Instrument Cathode-Ray Tube). Recorded specifications: construction Display / CRT, base Glass, socket 14-pin all-glass, maximum plate voltage 11000 V, and maximum plate dissipation 0.008 W. The archive does not yet hold a photographed example of this type.

ClassInstrument Cathode-Ray Tube
Base14-pin all-glass
Filament6.3 V @ 300 mA

Construction

Primary TypeDisplay / CRT
EnvelopeRectangular flat faced
Base MaterialGlass
SectionsSingle-beam

Filament / Heater

Heater NotesIndirect by AC or DC; parallel supply

Absolute Maximum Ratings

Typical Operation

ModePlate VGm (µmhos)Rp (Ω)µPlate mA
Typical Operation10000 V———0.01 mA

Application Notes

The tube should not be supported by the base alone; under no circumstances should the socket be allowed to support the tube. If full deflection capabilities are used, plates will intercept part of the electron beam; low impedance drive is desirable.
