NU-2160 Push-Pull


Schematic from Melvin C. Sprinkle (September 1951). The tube is known also as a 6BL5GT/2160.
It's a space charge grid amplifier, the two grids of the tetrode are inverted: the screen grid receives the signal and the control grid the screen supply. It's not the best amp but it is interesting from a technical point of vue.
