6С4С (=6B4G) directly-heated triode, made by Svetlana in 1978

Summary[edit]

Description
English: 6С4С (=6B4G) directly-heated triode, made by Svetlana in 1978. This tube, along with its three sisters, is working in my push-pull monoblock amps (albeit not every day), at 300V on the plate, for almost a quarter of a century. So far so good.
Русский: Триод прямого накала 6С4С (=6B4G). Эта конкретно лампа, вместе с тремя сеструхами, уже четверть века служит в моих моноблоках (пусть и не каждый день). Фиксированное смещение, 300 В на аноде. При перегрузе лампа светится синим как катушка Теслы, но вроде бы ей это не вредит.
