Description

The 6P14P-ER (6П14П-ЕР) output pentode is designed for amplification of low-frequency power.

The 6P14P-ER output pentodes are miniature devices enclosed in glass bulb and are provided with a nine-pin base and an indirectly heated oxide-coated cathode.

The 6P14P-ER electorn tube output pentodes are resistant to ambient temperature from -60 to +70°C and relative humidity of 95 to 98% at +40°C, as well as to mechanical loads: vibration loads up to 2.5g and multiple impact loads up to 35g.

These are premium quality Russian 6P14P-ER tubes. -ER (EP) suffix suggests they are rated twice as long service live (10,000 hours) as their cheaper cousins 6P14P-EV (EB)

All tubes new, military equipment and have "OTK" mark. Near equivalent: 7189, 6BQ5 and EL84M. The tube is manufactured by the Reflector plant, Saratov, Russia.
