I posted a couple of times that TN31's has continuity through the thermal pad of their emitter base on the stars (no apparent dielectric layer) - I did test this, but no one responded from what I recall. I believe AlexGT was the one who posted his detailed mods, one of which was filing down the thermal pad (step #8 here: https://budgetlightforum.com/t/-/17637), which I thought there was no reason to do. So, not getting any replies, not sure what went on - maybe he got an earlier version that had a dielectric layer? Not sure... Here, post #52: https://budgetlightforum.com/t/-/17637#comment-395402. Post #39 has the first mention of it and pics to show it. What do you think?
