With such low resistance it would be almost impossible to detect a dirt between 
individual windings but easy to detect sorts between primary and secondary and 
ground etc.

Joe,
I had my SB-220 opened up for other work and took the following readings:

HV secondary winding: approximately 11.8 ohms

Primary #1 Blk to Yellow: 1.1 ohms
                  Blk to Blk/Yellow: 1.0 ohms
    
Primary #2 Blk/Green to Blue: 1.1 ohms
                  Blk/Green to Blk/Red: 1.0 ohms

Your readings may vary somewhat depending on your digital meter and also how 
long you let the readings stabilize as the windings "charge up."

I also have a Peter Dahl hypersil replacement #SB-220-3 for my SB-220. The 
secondary measures 10.8 ohms on this transformer which has a higher current 
rating.

73, Dennis W0JX
