Notes
Cyrillic designation: 6П1. Uses a Soviet-specific rimlock base, not compatible with Western Octal or Noval sockets. Valve_equivalents.json lists the base as 'I/O' (rimlock/USSR internal designation). Designed for single-ended and push-pull output stages. Typical output power ~4.5W single-ended. Not widely available in Western markets. The 6P6S (6П6С, Octal base) is the more commonly exported Soviet equivalent of the 6V6. Pin Layout — Rimlock
