Thank you very much for your detailed response.

You're welcome. It sounds like you're ahead of me anyway. On
Usenet, "I need a schematic" requests tend to fall into two categories:
either "I don't know which end of a soldering iron to hold but I think a
schematic will tell me everything" and "I already checked all the easy
stuff with no luck and need a schematic to go further". I ass-u-med
that your query was in the former category but it was actually in the
latter.

First section is FET RF amp. Will look closely in that section

I know there will probably be some protection, tuning/filter, and
impedance matching components between the antenna input and the FET,
but to me FET usually means "easy to zap with static/overvoltage".
This is probably more true on equipment of that vintage.
