Think I got the burning question answered, but need some practical values. I put a 1 meg resistor from gate to source, and all seems well. But this is just in simulation, and not very accurate or reliable. I only have two IRF521 at the moment, but think I have a similar board some place. Pretty sure I can remove them without damage. Basically, I need to get this right the first time, or start over with a different part. Didn't really get how to calculate the resistors, just guessed...
