About the CTK 3-1
The CTK 3-1 is a power triode manufactured by Thomson / Thales. Thales high-µ coaxial metal-ceramic power triode with 5 kW output for industrial RF heating and oscillator applications.
Key ratings of the CTK 3-1 include tube type Triode, output power 5 kW, max frequency 120 MHz, construction Metal-ceramic coaxial, cooling Forced air and cathode Thorium tungsten.
Typical applications are industrial RF heating, plastic welding oscillators, wood gluing, induction heating and RF oscillators. Notable features: high-µ triode design, coaxial metal-ceramic construction, thorium tungsten cathode and thomson/Thales quality.
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.
