Description
Generator tetrode GU-34B in glass-to-metal design with indirectly heated oxide cathode and forced air cooling. Designed to operate as a broadband high-frequency oscillation amplifier at frequencies up to 250MHz and with an output power of at least 400W.
Works in a vertical position, pins down.
Forced cooling:
– anode – air at least 80 m3/h;
– legs – air not less than 80 m3/h
