I splurged on some lovely Spraque Atom axial electrolytics and Ohmite power resistors for the main chassis.
I figured I'd better focus on the charred looking area first.
Just as on the top, the gunk cleans off easily and the metal underneath is in excellent condition.
Not the easiest chassis to work on as some old waxy caps are buried deep.
Back topside for cleaning and tube testing. Only five tubes needed to be replaced.
Still much to do, but I figured this was enough for a full power up test.
