The '''Tektronix 015-0059-00''' is the early 230 V<sub>AC</sub> power supply version for the Tektronix [[134]]. It is identical to the 115 V<sub>AC</sub> version except for the cover, which has a different part number and voltage rating printed on it, and the addition of dropping resistors (2 kΩ & 2.7 kΩ, both 3 W) in series with the transformer primary. Oddly, this 230 V<sub>AC</sub> version appears to use a NEMA 5-15 115 V<sub>AC</sub> cord and plug. The addition of the two series resistors allows it to work from 207 to 253 V<sub>AC</sub>. | The '''Tektronix 015-0059-00''' is the early 230 V<sub>AC</sub> power supply version for the Tektronix [[134]].

The '''Tektronix 015-0058-01''' is the later 115 V<sub>AC</sub> version of the power supply for the Tektronix [[134]] Current Probe Amplifier. It differs from the 015-0058-00 in that it has a ~1 m AC power cord, an extended section of the housing to accommodate the power cord and strain relief, and a different part number on the plastic housing. | The '''Tektronix 015-0058-01''' is the later 115 V<sub>AC</sub> version of the power supply for the Tektronix [[134]] Current Probe Amplifier.

Each version provides an unfiltered full wave rectified 20-25 V<sub>DC</sub> output to the [[134]] amplifier. That output is filtered and regulated down to ~14 V in the amplifier. They work from 50 to 400 Hz and 103.5 to 126.5 V<sub>AC</sub>, or 201 to 253 V<sub>AC</sub> for the 230 V versions. The output is via a proprietary coaxial Tektronix connector. The negative side is held near ground by a pair of anti-parallel diodes and the center conductor is positive. | Each version provides an unfiltered full wave rectified 20-25 V<sub>DC</sub> output to the [[134]] amplifier.

The early versions resemble the '''Tektronix [[131]]''' power supplies ([[015-027]]), and the output connectors are the same, but they are not interchangeable. | |||
