I will ammend this--it seems there was some other arcing that I missed,
around NL601 (the side of the gray rectangular container is lightly
blackened and there's a nearby connector that seems to be blackened
slightly as well... hmmm, schematic would be useful here. Tempted to
get the Sams' Photofact, but for $20 for something I probably won't use
very much (and for such an old TV), might not be worth it.
