About the ITL 9-1

The ITL 9-1 is a power triode manufactured by Thomson / Thales. Thales ITL 9 series air-cooled metal-ceramic triode for industrial dielectric heating, plastic welding, and RF oscillator applications up to 120 MHz.

Key ratings of the ITL 9-1 include tube type Triode, construction Metal-ceramic coaxial, cooling Forced air, cathode Thorium tungsten and max frequency 120 MHz.

Typical applications are industrial RF dielectric heating, plastic welding, wood gluing systems, medium-power RF oscillators and industrial RF generators. Notable features: ITL series mid-range power, air-cooled operation, metal-ceramic coaxial and thorium tungsten cathode.

Power triodes are three-electrode grid tubes used as RF oscillators and amplifiers in industrial RF heating (plastic welding, induction heating, drying), RF-excited CO₂ lasers, broadcast transmitters and particle accelerators. In oscillator service they work with vacuum capacitors in the tank and matching circuits.
