The Tektronix Type 128 is a power supply for Type P500CF cathode-follower probes. It was introduced in 1958. It provides two voltages to the probe: regulated +120V DC, and unregulated +6.3V DC. Low voltage rectification is done by a selenium rectifier. Higher voltage rectification is done by a 6X4 tube.
