Well, I pulled most of the tubes and with the 5u8 still in place the 115 is zero volts.
I started putting tubes back on and found that the once the 12au7 is installed the 115 line jumps to 50 volts, the 6au6 and the line jumps to 115.
Ok, I took them to fair radio and tested them on a TV-7 tube tester and they show good.
I sub in other tubes and I get the same results....
each tube has both 115 and 265 being fed to them but there isn't a path to each other I can find unless both have ceramics to ground that are shorted but wouldn't the chassis be live then?
