testing currently underway. Don't order LEM 500 yet (or LEM 600 might be better?). Here's the plan:

Try to get latch up of LEM 500. If I can't, remove R6 (temporarily) and try to get latch up with LEM 300, just so we know with certainty that the output of the lem (through noise pickup or whatever) is causing latchup.

Back to testing! Son will wake soon. don't have much time! haha!

EDIT: It may be better to have D8 and D9 on other side of R6 if things continue to be a problem with latchup. We'll change it if we have to! ya!
