Default S-38 Questions about alignment.

I am restoring now aligning a S-38. Yep, all caps and resistors replaced
except the domino caps and tubes tested, bias voltages with in spec. I gave
up the alignment for now. I am having trouble aligning the Band 2 at 5mc.
The oscillator just dose not want to go high enough. Perhaps a good night's
sleep will help.

Questions:

1) What is the oscillator offset (add or subtract the IF freq 455) for the
four bands? Are any bands different from the others? Broadcast is just
fine at frequency plus IF (455).

2) Are the domino caps paper inside or mica? They are NOT Micamold. There
are three of four of them. I was going to replace them next and heat gun
the coils.
