That "happy little accident" line is so good. It's wild how someone who doesn't know the rules can just cut right to the point. I mean, we get so stuck in the steps sometimes we forget the whole thing is supposed to look good, not just be correct.

Yeah grounding loops are the worst, they just show up out of nowhere. It's always some tiny change you'd never think about, like a new power strip or a different cable run. The ringing is so distinct though, once you've heard it you never forget that sound. We ended up putting ferrite cores on everything as a band-aid until we found the real source. Took forever to trace it back to a single bad outlet.

Yeah, @uma_nelson85 gets it, this is just how old tech fights back.

My fridge was a paper avalanche before my corkboard.

Honestly, that's a solid tweak. I've had to do something similar with a 6A before, bumping up the color to developer just a bit. Those old dyes can be such a pain to lift evenly. Makes you wonder why the standard ratios don't always cut it, right?
