About Adjusting 4.5 mc trap/Sound Take-off in a Single Coil Can??

[Jon1967us]

I fairly new to alignment and am trying to perform one on a TV video/sound panel on a '59 Philco TV.

The schematic and alignment instructions indicate that there's a "top" adjustment for the 4.5 MC trap and a "bottom" adjustment for the "sound take-off"

So, am I to understand that I need to access the bottom adjustment from under the dual coil can (which means that I need to undertake to remove the staked circuit board, which isn't a small undertaking) or am I missing something?

Also, it appears my other needed adjustment includes a 4.5 MC IF Interstage transformer. However, it appears that the unit is damaged, as I can't seem to probe and find the adjustment screw inside. I think it broke off from overzealous adjustment long ago (?)

Can the transformer be repaired or do I need to just locate a new one? Are all 4.5 IF transformers pretty much equal in value and it's just a matter of matching size, board mounting specs?

Thanks for any help!!!
