Here is a ICT Comm Series, model ICT12012-10A power supply.
Complaint: Folds back to 9.3V under load (40W VHF radio).
So I open this up and see nothing visual. Took another look with my ESR meter. AND? Yeah, all caps besides the main filter cap are bad. It got a full recap, including the main filter cap.
Replaced: C7 200V 330uF, C10 35V 22uF, C15 35V 100uF, C18 35V 47uF, C 27 35V 10uF, C28 63V 47uF, C32 and C33 16V 2200uF.
Another PSU saved from being tossed into the bin.
