Description
The Russian 6R4P (6P4П rus.) tube is a dual pentode for use as a low-frequency and video signal amplifier (first pentode), LF and intermediate-frequency voltage amplification and generation, a sync pulse selector, and a keyed AGC detector (second pentode), and in radio equipment. The cathode is indirectly heated oxide. Base – 10 pin.
Close analogues of 6R4P are tubes EL36, 6CM5.
