1945 PE-237 Vibrator Power Supply Troubleshooting Procedure and Demonstration

You're in deep if you're watching this video on the old PE-237 vibrator power supply. Welcome to the club, and I hope this helps you fix your system. The PE-237 in this video stopped working suddenly and would consistently trip the unit's circuit breaker whenever it was put into high-power/heavy-duty mode for radio transmitter usage. In the video, I walk you through my troubleshooting process including schematic diagram review, step by step component checking, and finally, a demonstration of the power supply working again. If you find yourself in a similar situation, you've got to get your hands on technical manuals. Especially for the process of disassembling the radio to get at the components from underneath the chassis. TM-263 is essential for repairing one of these old vibrator power supply units.
