To avoid confusion, since I have assumed a new avatar, I was previously represented as:

My question today:
I’m currently engaged in the electronic restoration of a Model 60. My first step in any project to check continuity through all coils. I’ve been very lucky with power transformers, but this one concerns me because my secondary coil resistances show more variance from the original specs than I’m used to…

…and the set has been operated with a supplemental 8 mfd cardboard electrolytic condenser, and I don’t know if that has the potential to damage the transformer. The primary coil checks out at 11 ohms.
So, Philconians, should assume the transformer is OK, or should I test it out before putting a lot more time into the project? I’ll be most appreciative for any advice.
Thanks,
Henry
