Skip, just to clarify a couple of things. Did you replace all the wax caps and and any out-of-tolerance resistors? Are all tube shields in place?
You mentioned earlier that the AM band aligned properly, does AM still play OK? What signal generator are you using, and do you have another working radio with SW (or a frequency counter) to verify it is putting out the correct frequencies?
Lastly, can you list, step-by-step, the exact procedure you are using to do the SW alignment? Sometimes it is a simple thing we are overlooking that causes us problems, so maybe someone will spot something you're missing.
Here is a link to the schematic and alignment info for anyone who wants to help:
