NEW TUBES 6P1P-EV (6П1П-ЕВ) Tetrode is equivalent of 6AQ5A, 6AQ5W, EL90, 6BW, 6CM6.
The 6P1P (6П1П) is a Soviet-made miniature 9-pin beam tetrode
vacuum tube with ratings similar to the 6AQ5, EL90 and the 6V6. Because
of a different pinout (a 9-pin base versus 7-pin base) than an
6AQ5/EL90, it cannot be used as a plug-in replacement for these types;
however, it will work in the same circuit with component values
unchanged. Its maximum plate/screen voltage and dissipation ratings are
actually slightly higher than a 6AQ5. A ruggedized/extended ratings
version of the tube is designated 6P1P-EV (Russian: 6П1П-ЕВ), roughly
equivalent to the 6AQ5W. A Chinese-manufactured version of the tube also
exists, labeled 6P1.
The type was commonly used in Soviet-built
vacuum tube radios and TV sets as an output audio amplifier, until it
was replaced by the higher-performance 6P14P (an exact equivalent of the
EL84).
The tube is no longer believed to be in production.
Overall dimensions of tetrode 6P1P-EV:
- lamp height - 72 mm;
- lamp diameter - 22.5 mm.
Weight no more than 20 g.
Operating time not less than 7500 hours.
