I'll be performing an alignment shortly on my Zenith 9-S-262 and have a few questions.

Operation #1) It says to connect the signal generator to the 1st Detector Grid. I I looked at the tube compliment and description in the Socket Voltages table:

I did not see anything listed as the "1st Detector". Is the "1st Detector" the 6K7 RF tube? If so, I believe I would connect the signal generator (through a 0.5 Mfd cap) to the clip on top of the tube. If this is the case do I leave the clip attached or remove it?
Operations #2-4) I guess the term "Dummy Antenna" is throwing me. I always thought a dummy antenna was just a feww feet of wire rolled up with one end connected to the generator. The rolled up wire would then be placed close to the radio, but not connected to it. Sounds like the instructions are telling me to connect the generator to the antenna post through a 200 mmfd cap. Pleae confirm. I'm familiar with the "rock gang" procedure.
Operations #6-7) Am I connecting the generator to the radio through a 400 ohm resistor?
Thanks,
Geoff
