> I also found out whatever the other control is
That would be #4 and it's used to fine tune the ant stage.

> Also can this unit be aligned
Yes it can. There are 3 trimmers in  front of the tuning cap. These are use to set the dial frequency.  There are 3 more behind the tuning that have access holes though the chassis, don't mess with those they are for neutralization.


> I still also seem to have some obnoxious static coming through along with a slight hum, any way to get rid of those?
If the static is electrical in nature like light switches or arcing from motor brushes it's going to be difficult to get rid of. Having a good ground connection to the chassis will help and will help w/ the hum. And having the bottom cover on too. There is a hum adjustment pot over by the power transformer and 80 tube. Adj it for minimum hum
