6C33C-B (RU) – 6S33S-V
These triodes are intended to work as regulating valve in electronic stabilisers of voltage.
They consist of two triodes (A and B) in the same glass envelope. Cathodes, grids and plates are
internally connected in parallel. The filaments are lead out separately for each triode.
