6F12P tube. HF triode-penthode
The 6F12P wide-band triode-pentode has been designed for use in frequency converting stages and high-frequency or low-frequency amplifiers.
Cathode: indirectly heated, oxide-coated.
The 6F12P (6Ф12П) wide-band triode-pentodes are resistant to ambient temperature from -45 to +70°C and relative humidity of 95 to 98% at +25°C, as well as to vibration with an acceleration of 2 g.
All tubes new, military equipment and have "OTK" mark. Near equivalent: --.
The tube is manufactured by the Nevz, Novosibirsk, Russia.
