Even before I power up I want to replace the electrolytics based on age

Being away from parts suppliers for 10+ years leaves me ignorant of what is
where. Therefore my original question: "What is a good source for electrolytics?"]

Digi-Key, Mouser, and when you absolutely need can caps, Antique Electronics
Supply. A phone call to 1-800-DIGI-KEY for a catalogue will be an eye-opener
if you remember what their catalogue was like ten years ago. These days it's
bigger than Newark or Allied.
