Description The 6N6 is a heater type output tube comprising two triode units mounted in a common bulb. The smaller (or input) section acts as driver for the larger output unit and is directly coupled to it. The input cathode and output grid are connected internally. The tube operates without bias so there is no need for a cathode resistor and it's associated by-pass condenser.
Since the output section operates with a positive bias, it requires a high-µ characteristic to keep the plate current low. This is achieved by using two separate control grids connected in parallel inside the bulb.
