Today I decided it was time to remove that RF assy.
After unscrewing the posts and snipping wires, it was still being held in place, and I almost gave up, but then I calmed down and found things that were holding it (wires to the tubes' panels). Actually not that many. There it is. The assy and what is under it.
Many wires are rubber-insulated, so will have to be replaced. They used a medley of wires, some with rubber insulation and some cloth-covered.
Other than that, I had to remove the interstage transformer and realized one half of the secondary is open (strange, usually it is the primary).
Also I tested the tubes, and 2A7, the pentagrid, the first I tested it, somehow did not even move the needle; then I took it out, checked the filament, gave it the look, and put it back. I worked, but it was SOOO weak, I do not think it is usable. Will have to buy a new one. Actually, might borrow one from the other two radios.
The rest of the tubes all test strong to very strong.
Also I desoldered/clipped everything going to the tuner cap. It is very dirty and needs to be washed.
So far this is it.

People who do not drink, do not smoke, do not eat red meat will one day feel really stupid lying there and dying from nothing.
