Kenotron
The Russian 1C11P / 1Ö11Ï vacuum tube is a high-voltage
kenotron with the oxide cathode of direct heat.
It is intended for the rectification of pulses in return
motion or sweep flyback pulse voltages of line scans in
television receivers. This tube
requires a miniature 7-contact socket.
Longevity is a minimum of 1500 hours.
