One update - the second deflection board had an open D702, which someone
had replaced with a 1N4004. I swapped in a 1N4002, which is still beefier
than the 1N4001 that came with it. The "eats transistors" board now
appears not to eat transistors, but I haven't left it on that long. It
powers up with vector clatter but the spot killer remains on.

FWIW, the "bad Y-amp" board is a stock P314, and the "eats transistors"
board is a P314 modified with the "protection board on stilts" hack.

Later,
Doug.
