Scott:

Only the filaments have AC, on the other pins you need to test for DC. Most meters require that you switch between AC and DC (mine does anyway). You may still get high readings, but at least they will be accurate this way. I'm still guessing there's an error somewhere and you will need to trace the B+ from the source, make sure the cathodes of the tubes are connected properly and so on. You are testing the right places, and the probe makes no difference. There are other things that can cause a tube not to conduct and so raise the voltage.
