The '''Tektronix 015-027''' is the 115 V<sub>AC</sub> power supply version for the Tektronix [[131]]. It has a standard NEMA 5-15 AC power plug built onto the body of the power supply. It has a full wave rectified output which is filtered and Zener regulated to ~20 V<sub>DC</sub>. | The '''Tektronix 015-027''' is the 115 V<sub>AC</sub> power supply version for the Tektronix [[131]] Model 4.

The (please add) is the 230 V<sub>AC</sub> power supply version for the Tektronix [[131]]. 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 a metal extension of the body to accommodate the addition of two dropping resistors (18 kΩ, 1 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 210 to 250 V<sub>AC</sub>. | The (please add) is the 230 V<sub>AC</sub> power supply version for the Tektronix [[131]] Model 4.

Both versions have a Tektronix proprietary coaxial output connector. The center conductor is grounded and the outer conductor is about 20 volts negative. | Both versions have a Tektronix proprietary coaxial output connector.
