112A DHT Preamp Part Hummmiliator

I’m scraping my single chassis plan. I’ve ripped out the power supply minus the IT. The noise in the power supply is now gone so yay for a singular victory. For troubleshooting I used solid-state diodes as I was turning the preamp off and on a lot. There is still a massive amount of hum. I am incapable of getting rid of it or decreasing it so far. I took a break from the testing rig and listened to some Ministry and BillyGoat. I can tell it sounds sweet in there somewhere with bench B&W speakers but if there is hum there can’t imagine the levels on big horns.. There is a lot of clip leads going on and no amount of moving or changing affects anything. Is this my first electronic abortion? Maybe. Not giving up yet but getting close. There is either something super weird going on or broken or I missed something ultra basic.
