Apple Mac SE/30 Analog Board and PSU Restoration - Mac SE/30 Part 4

For the extended video click here: https://youtu.be/O0-63sDOfm8

In this video we restore the analog board and power supply for the SE/30 project. This is specific to the Sony CR-44 version power supply. We replace the electrolytic capacitors, reflow the boards and insulate the flyback transformer with some corona dope. Once these are finished we will have all the major assemblies ready to go and will finally be able to assemble the machine in the next video.
