Oh, believe me, if a problem exists, it finds its way into my life.

Yeah.  I'm looking at the schematic, and unlike the Mac analog board
which obviously has lots of caps all over it, this Apple II design
seems almost purely TTL... with one final output transistor (2N3904)
prior to video out.  I see no caps in the video chain at all.

Michael, do transistors "leak" the same ways electro caps do?
