OK, while touching grids, I realized the buzz stops at 1st Det, checked the voltage at K, was 54V. Too much.
The cathode flexible resistor 2kOhm was opened.
Changed it.
Now it is normally receiving BC band and at two SW bands.
The last one does not get anything...but then I just looked at the dial, it is 1.5MC to 4.5MC...I am not even sure it is supposed to get anything.
Anyways, I will attempt the alignment tomorrow, this will show if the band is working.
But.....I wasn't hoping it would sing today, so.....nice end for the day.
