155-0032-00

The Tektronix 155-0032-00 is an amplifier chip made by Tektronix. It is packaged in a 16-pin DIP. It is used in the 335. The inputs and outputs are differential. The input differential amplifier's emitters are brought out to pins 1 and 16 for the emitter current source and the frequency compensation.
