On the 80 rectifier measure the voltage from cathode to plate that's on the transformer #6 to #9  also measure from cathode to chassis ground. What are these voltages?

On the 80 tube there are 4 pin F-F (the larger  pins) and P-P (the smaller pins) I measured them in the chart before. (the P-P) is the plate to cathode) right? as for cathode to ground how do i measure that? I assume one of the smaller pins to ground and does it matter which one. Is this right. This is my first radio and I'm doing a lot of research but still way behind you all.

thanks ken
