Heater wiring looks correct on the preamp tube. I can’t make it out on the power tube. It looks right on the regulator as well but I’d double check just to be safe. Because your indicator light is dead and nothing glows, I still think the heaters aren’t getting voltage. think the safest way to test is pull the tubes and check if you’re getting heater voltage at the indicator or whether there’s a short somewhere there. You can check most of the heater voltages by probing the tube sockets.
