The 4CX250F (7204) (P/N 154-0300-00) is a beam power tetrode vacuum tube designed to operate up to 500 MHz with plate voltage up to 2000 V.
It was originally designed as an RF power amplifier tube for transmitters and requires forced air cooling.
The 4CX250F is the same as the 4CX250B (7203), but with a 26.5 V filament instead of a 6 V filament.
