Triode The YD1212 is a powerhouse in the realm of ceramic-metal triodes, showcasing its thoriated tungsten cathode and the state-of-the-art hyper-vapotron cooling system for the plate.
This remarkable tube achieves a maximum plate dissipation of 120kW and is engineered for peak performance up to an impressive 30MHz.
Expertly designed for oscillators, this tube is the perfect choice for high-frequency heating applications within the industrial sector.
Versatility at its best, the tube serves as a direct replacement for both the BW1185J2 and ITK90-1 models.
