Heathkit HP-23 Power Supply Refurbishment printed circuit board
This power supply printed circuit board allows you to refurbish the ancient HP-23 series of power supplies for the HW-100 and SB-100 series of Heathkit SSB/CW transceivers.
Use 450-volt capacitors and 1KV rated 1N4007 diodes. There are several LED diodes involved -- these make it easier to see if the various supplies are working.
Mount the printed circuit board above the old chassis with standoffs.
