>On the pin voltage testing. To access the pins on the 6F6G tube it looks like I may have to unbolt that wire wrap resistor from the chassis and pull it out of the way. Is that correct?
If you do make sure that you do not lose the ground connection at the end of the resistor. Don't know if it is though a lug to the chassis though the bolt that holds the resistor or there is a wire going to a ground lug. Without that connection there will be no negative return (B-) for the power supply.
Your 9K resistor is the high voltage feed for the mixer tube (6A8 ). Best case set will work with low sensitivity worst case not enough HV to make the local oscillator run hence no reception. Won't damage anything.
