@King Fan thank you so much for the complement and excellent advice (especially bullet 3 - never thought of this!). I didn't realize that my images don't expand as large as they show on my phone, so I plan to post close-up shots of the filament wiring. @D'tar what you may think of being OCD is actually genius! You can check continuity of the traces without lifting the circuit board!! Plan on me implementing your idea in this build.
