static/crackling in left channel

It's entirely possible it has to do with the jack. Usually the black wires there are normally the culprit. Maybe try moving them around, adjusting them while the heat is on. Plus make sure all the wires at terminal 3 are secured well.

i reflowed all the black wires, including the LEDs and the switch. no change. also had my wife take a listen to make sure im not losing my mind and she hears it too.

here are some pics. i tried to get as close as possible and capture every joint.

The left RCA jack ground lug and the chassis earth lug by the power entry module do not look adequately soldered, just as an example.

reflowed those 2 connections. pics attached. didn't change anything. then tried to go over a bunch of joints and reflow them and now i actually think it sounds worse. so it probably is something to do with a soldering joint but short of redoing the entire thing, not sure how i can isolate it.

The last "flow" pic basically hasn't. I use Cardas solder and it flows easily and gives a smooth finish. I use #7 bits in my old Weller solder station. It has no adjustment. If this pic shows a joint similar to others in your build I would say that upping your technique would be a useful move.
