will keep looking for that cap replacement trick.  Just happend to notice the alignment page.  Right under the knobs there are 4 trimmer caps.  1 big and 3 smaller ones just like underchassis picture.  In the middle of the chassis theres supposed to be 3 small ones(only has one large screw trimmer), and twards the rear supposed to be 3 more(only has one small screw trimmer cap.  The center, and rear only have 1 trimmer cap.  how many different versions of this 37-630 are there?

Beginning to wonder if this is a 37-630 chassis at all since its missing trimmer caps.  It does have the same tubes and layout of the 37-630.  The console cabinet itself has the 37-630 sticker in it.  Wish I could post a picture on here but haven't figured out how yet. 
Have now replaced the 2 under tuning gang caps.  Removing the tuning gang wasnt that hard, reinstalling it was ....insert colorful metaphore here.  Replaced 2 weak 6k7 tubes with nos and replaced the 6q7 as well.
