Important Safety Note: Working on or testing equipment such as the Heathkit HW-101 transceiver and the HP-23 power supply is extremely dangerous since very high voltages are present when the equipment is turned on, and may even be present when the equipment is turned off and unplugged. If at all possible, do all work with the equipment off and unpluggedand be sure that the capacitors are properly discharged before working on the equipment. The operator assumes all risk and liability in such matters! Do not work on this type of equipment unless you are experienced with working around very high voltages!
Though the complete schematic diagram can be found in the Heathkit HW-101 Manual (file pages 239, 240, and 241) the diagrams here are notated and much easier to follow. The sectional schematics are formatted to print well on 8 1/2" x 11" paper in landscape mode. Since the notations are in red, the schematics should be printed in color, if possible.
