Hi and welcome to the forum. Your voltage readings seem to be off. Be sure to have the negative side of your meter connected to B- and not the chassis. A convenient location would be at the negative side of the power supply filter capacitor. The voltage at the junction of 20 and 22, two 10K resistors, should be around 85 volts. Also, when you touch your probe to the grid you are effectively attaching an antenna to the grid, so you will hear radio stations.
