On my 41-220C I'm checking all coils.  The one I have a question on is #26 (2nd IF transformer).
I have continuity on both coils but I am concerned with the resistance reads.  These were done under the chassis with everything still installed.  On the primary side which goes to the plate of 7B7 schematic shows 60 ohms and I read 11 ohms.  On the secondary side going to the diode of 7C6 schematic shows 8 ohms and I read 14.7 ohms.  Should I be concerned?

I wouldn't loose any sleep over it. The acid test is when you get it working will it peak up @ the proper frequency.
