NEW Power Supply (PSU) for Mac SE & SE/30 [Baby Face Electronics]

I compare this new Mac SE & SE/30 power supply with the stock SONY PSU and popular SEASONIC. See how to upgrade your Main Wiring Harness with 16AWG wires! Learn how to discharge the CRT and properly remove and later reassemble the power supply and analog board. My test rig included a Micron Xceed MacroColor 30HR PDS video card & Grayscale Yoke Adapter, CPU-socketed 50MHz 68030 Daystar PowerCache accelerator, custom ROM SIMM from Kero's Mac Mods, and a Quantum spinning platter HDD.
