About the CTK 5-2
The CTK 5-2 is a power triode manufactured by Thomson / Thales. Thales coaxial metal-ceramic power triode delivering 10 kW output, CTK 5-1 series variant for industrial RF and oscillator circuits.
Key ratings of the CTK 5-2 include tube type Triode, output power 10 kW, max frequency 120 MHz, construction Metal-ceramic coaxial, cooling Forced air and cathode Thorium tungsten.
Typical applications are industrial RF heating, plastic welding, wood gluing, RF oscillator systems and dielectric heating. Notable features: 10 kW RF output, CTK 5 series variant, metal-ceramic coaxial and high amplification factor.
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.
