I've been blessed!

Well, I disconnected all the test gear and put the chassis back in the cabinet. Picture looks OK, but the problem with the sound volume getting low when the fine tuning is correct is now worse. OOPS - forgot to turn the page in the instructions and do the last step where one sound trap is deliberately detuned to get the sound carrier 22 dB below the video.

Well, since I understand what they are shooting for, I am going to try detuning it "by ear" while listening to the sound on the test pattern disc. Strange thing to me is that they say to detune it, but they don't say which way. I would think it should go towards the upper adjacent channel, that is, lower in frequency at IF, so it is moved away from the edge of the chroma. So, since I can't tell which way is which without the sweep, I will try both ways and see if there is any bad effect in the picture one way or the other.

This brings up a question: should the sound volume be so sensitive to the sound carrier amplitude? Can someone with a similar set try the fine tuning and let me know if it affects the sound volume strongly? If it doesn't, I should be looking for some sound trouble. BTW, I did check alignment of the sound section, so I know that's not it.
