Rich, KE0ZX has supplied the web page link for the SEITS web site (very good
article).
Here are a couple of additional resources for your Astron repair:
Schematics for the Astron power supplies

KBT DC Supplies (Spec sheets on 723; 3055, & 3771)

While the fold-back could be an issue, you should check the
pass transistors (2N3771 or 2N3055) and LM723 regulator.
