Can you tell me what are the major things to replace when rebuilding a power supply for a Data East Simpson. Thank you. I want to try doing this myself!

Most DE Power supply were direct clones of Williams power supplies. A Williams system 7-11a kit will have most/all the parts you need and can be gotten off of Ed at GPE.

Note: He is currently out of the 100uf 100vdc caps (which is why the 'kit' is out of stock) so just list what is in the kit and order the piece parts.
