Power Supplies for the Tektronix Type 134 Current Probe Amplifier
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.
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.
The Tektronix 013-0050-00 battery adaptor, allows the Type 134 to be powered from any 22.5 V battery capable of delivering 70 mA. Note that, due to the complete absence of ground connections, this accessory could also be used for the Type 131.
The latest version (please add) of the Type 134 power supply appears to be a Tektronix branded wall wart with an AC line cord and output to an inline connector.
Each version provides an unfiltered full wave rectified 20-25 VDC output to the 134 amplifier. The negative side is held near ground by a pair of anti-parallel diodes and the center conductor of the output connector is positive. 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 early versions resemble the Tektronix 131 power supplies , with the built-in AC power plug, and all the output connectors are the same, but the 131 power supplies and 134 power supplies are not interchangeable, due to the difference in grounding.
