     What a lot of work! Congratulatons!  I would not bother to leave 
the bathtub caps in place but would remove them and mount terminal 
strips in their place, maybe I misunderstood and this is what you plan 
to do. I did the same thing when replacing the leaking oil-filled paper 
caps in my RCA AR-88A. I have a couple of SP-600s on the back burner 
that probably need new bathtub electrolytics and will do them the same way.
     What is the problem with the IF crystal filter? Perhaps its not the 
crystal itself or perhaps it can be fixed by baking. Even when ICM was 
still in business they told me they did not have such crystals.
