I did get it wired with power to the heaters but most of the tubes are not getting the voltage they should. The 35Z3 is at 29v and the 50L is at 42 the others are a little low as well. I might have a miswire but there is many wires to replace even though I’m not seeing any obvios shorts it’ll be more important to rewire before getting power fine tuned.
