Has anyone experienced a 48-248 with no SW and found the fix?

I have no SW reception and a scope shows no osc in SW mode. SW osc coil coninuity is OK.
Total recap exept for the mica types. All resistors checked and most replaced including some very hidden ones.
AM and FM work pretty well. I have aligned the IF but not touched the front end. I have swept the SW band with a signal generator with no result. I'm working from a Riders manual and the detail is poor and correct ID of the Mica types not good. I realy don't want to do a mass change out of these unless I have to.

Any ideas ?

Still need a power transformer but a smart tap "healed" this for now.
