Hello Julian - the 110 is a great radio.
Ha! I just got done with the IF alinnment on a 110 VHF model.
That was after removing 1" of tar and nicotine from every reachable inch of the radio.
What a mess it was. Blech. TSP is great stuff.
Anyway, the 6BE6 bus line is an open flat exposed (uninsulated) "strip" coming off the 6BE6.
You can't miss it. Perfect for attaching your probe.
If you can't find it, I can send you a picture.
I'll leave to others to answer #2 & #3.
Kind regards - Mike KC2OSO.
