Q1. I am not aware of any production changes in the early (2-45) Model 90. I would guess that whoever removed the RF choke and one of the caps from that 2nd detector filter network also miswired resistors (33) and (47). I don't have a 2-45 90 to compare.
Q3. Since I still have not unpacked all of my material, I am going to defer to Chuck who, I am sure, will chime in here within the next 24 hours. If my info is incorrect (and it may very well be), I'll have to correct it. 
Q5. Again, I am going to defer to Chuck, same reason (material still packed up).
