With most, if not all, Philco AC/DC sets the chassis and B- are isolated from each other so you can't use the chassis as a reference point for voltage measurements, you use the AC switch on the back of the volume control. In any even something is definitely not right if you are measuring 150 VDC from the cathode of the 35Z3 tube, it could be an open field coil or a dead resistor in series with the B+.
