I have some good news and some bad news.

Bad news is the power supply still ticks even after adding another diode of the same type with the existing one. https://68kmla.org/forums/index.php?/topic/23952-macintosh-iicx-psu-problems/

I said I got two new diodes, but I only ended up getting one.

I do hear temperature is important in startup. I am working on this in a 45F garage, so I might move it inside then try it again in an hour.

Good news is you can hear the chime every time the power supply clicks, so the board recap was successful!
