[R-1051] R-1051 IF alignment - advice?

[Nick England]

One of the few instances in my life when I looked before leaping. Or asked the list before leaping. Whatever. 

I have taken Paul and Ray's advice and left the slugs alone. So far it looks like 3 IF/AF modules that I worried about are OK after going through the AGC adjustment process. My inexperience/stupidity for not realizing that on this rig a) you can't turn AGC off and b) there are 3 gain adjustments to get wrong. 1 module really does seem to have a sensitivity issue and no AGC action so I'll investigate that later. 

Thanks guys for saving me from myself!
Cheers,
Nick
