6N6MG

The 'Triadyne' 6N6MG is a heater type output tube comprising two triode units mounted in a common bulb. The smaller or input section acts as a driver tube 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.
Registration assigned to Triad Mfg. Company, Pawtucket, RI, USA.

6N6MG was the compact, octal-based and metal-shielded version of the 6B5 introduced by the same manufacturer at the beginning of the same year. Application notes loaded to the 6B5 can be applied to 6N6MG.
