Sounds like the BalUn was doing a superlative job.

Hi Owen,

What you describe (sans the problematic word latent) is specific heat
capacity. And just like any capacitor, charge/heat does not increase
after a source is removed. If it is not removed (which I presume was
the intent of both your statements), then the specific heat capacity
you describe is a design boon.
