you guys that have predictas know the drill, broken tube socket right where there is a bridge between the pin socket and the pin insert to the pcb.
checking for continuity with the tube out (touch the probe to where the pin goes in and then the other side to the pcb shows good continuity. insert a tube socket extender with test points and try it again, now no continuity, moral of the story is if you see a predicta like tube socket, and something is not right, better check it with a tube socket extender to simulate an actual tube pin inserted. I have the correct tube socket so will replace it soon.
