"The PA555 uses one 12AX7 tube running at 150 volts. The input signal is connected directly to the grid of the tube and all of the gain of the PA555 is from the 12AX7 tube. The out-put section is a pair of emitter followers to drive the output. The PA555 has a no feedback circuit or integrated circuits in the audio path, it is all analog" - Bellari
