The effect of decoupling the PI, for me, seems to be more important than the voltage. Although, maybe do a 2.2K since your B+ is on the low side.

Okay, so here is what I have currently

-------------------------V3(260ish)------V2(200ish)------V1(190ish)
-----------430-------------420--------------316---------------310
300ohm----|----1kohm----|----22kohm----|----2.2kohm----|----150kFET

If I change the string, here is what I would expect

-------------------------V3(245ish)------V2(200ish)------V1(190ish)
-----------430---------------410--------------316---------------310
300ohm----|----3.3kohm----|----18kohm----|----2.2kohm----|----150kFET

So I have reduced the voltage to the PI without doing the same elsewhere. Now, why would I want to do that?

Thanks, Scott! If you feel like it, I'd love to hear more. I'm here to learn.
