Description

The 6180 is a double triode designed for trustworthy operation under conditions of vibration and meohanical shook., The heaters of the two triode units are conneoted in series, so that failure of either heater rerders both units incperative, The electrical charscteristics are similar to the 6SN7GT, but the maximum ratings have been reduced.
