I have other 80 tubes and I get the same, the more I look at the power side from the 42 through the 80 I'm seeing issues like the 5 pin (Cathode ) from the 42 is not going to chassis as the print shows but is routed through 2 resistors 250 ohms each I get 514 ohms total. The center tap which is supposed to go through a 250 ohm resistor is tied to the chassis directly. So I need to go through this line by line to see what they have done.
