CPI ML-7482

The ML-7482 is a vapor cooled, ceramic/metal,
medium-mu power triode designed primarily for
use in industrial radio frequency heating services.
Its vapor cooled anode is conservatively rated for
200 kW of plate dissipation. A glazed ceramic is
used to make insulator cleaning easy. Input of 640
kW is permissible up to 30 MHz. Plentiful reserve
emission is available from its 6525 watt filament.
The grid structure is rated at 2.5 kW, making this
tube an excellent choice for industrial service.
