The Tektronix 015-0058-00 is the early 115 VAC power supply version for the Tektronix 134. It has a standard NEMA 5-15 AC power plug built onto the body of the power supply.
The Tektronix 015-0059-00 is the early 230 VAC power supply version for the Tektronix 134. It is identical to the 115 VAC 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 VAC version appears to use a NEMA 5-15 115 VAC cord and plug. The addition of the two series resistors allows it to work from 207 to 253 VAC.
These early versions resemble the supplies that came with the Tektronix 131, and the output connectors are the same, but they must not be interchanged.
The Tektronix 015-0058-01 is the later 115 VAC 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 015-0059-01 is the later 230 VAC version of this power supply. It differs from the 015-0059-00 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.
Each version provides an unfiltered full wave rectified 20-25 VDC 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 VAC, or 201 to 253 VAC 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.
