I have a copy of the PCjr Technical Reference Manual.
I bought a PC-Jr for
my brother years ago and got the Reference but never used it. "L@@K RARE
computer book".
On page 2-135
"The system power supply is a 33 watt, three voltage-level, two stage
supply"
Appendix D-1
Transformer
Input: 110 Vac 60Hz
Output: Pin 1 - 17Vac, Pin 2 - GND, Pin 3 -17 Vac
I put scans of the internal Power Supply schematic and PCB here:
