I just didn't feel good about this set not working well and found a parts chassis at Ktown so I pulled it apart again. Its always in the details.... I was losing signal around the 2nd IF transformer and the reason was not the transformer but faulty recapping by the repair guy  . I had the 0.05 cap circled in green connected to pin 4 of the 1LD5 rather than the correct position of pin 3.... ack! I had already modified the 2nd IF transformer by swapping out caps and they were not the correct value. I was getting signal through but could not really peak it properly. Terry pointed out that I should probably have something closer to 100pf caps in there while I used 82s. Anyway, since I had already picked up the parts chassis I swapped out the 2nd IF transformer from it and the set aligned nicely and I'm getting all bands at nice volumes. Thank you to each of you who commented and helped along the way and especially thank you Terry (Radiorosyln)! I can now get this set back to its owner in decent shape.
