Excellent suggestion - thanks!!

Question - looking at the schematic - I started with looking between G of 24 and Chassis Ground at the Detector , and saw continuity. I then looked between G of 24 at and Chassis Ground - and saw continuity (I believe this is the Second RF). Finally - when I looked at G of 24 and Ground of #1 - and saw open. I would then presume that the First RF coil is open - which would be Schematic part number 7?

Let me know if my thinking/thought process seems logical - I am presuming that going from the Grid connection to chassis ground would be testing the integrity of the coil which terminates to the ground or chassis.
