Notes

Cyrillic designation: 6Н15П. The 'П' suffix denotes civilian/industrial grade.
Each triode section: mu=5.3, Rp=2.5kΩ (approx), Gm=5.3 mA/V at Va=150V. Maximum plate voltage 300V, maximum plate dissipation 1.5W per section.
The 6J6 (RCA) and ECC91 (Mullard) are the Western equivalents with the same Noval pinout.
Primarily used in VHF oscillator and mixer circuits, including UHF television tuners.
