RE: Aluminum tape on toroids? What about the sticky side being nonconducting?

I had always assumed that dielectric breakdown was almost instantaneous,
so even if it acted as a capacitor, it wouldn't do so for long.

Hi Jack...

the adhesive makes no difference...   whats a 10thousandsth of an inch
going to matter compared to 36" of streamer...   besides, if it did act
as
an insulator and added extra capacitance, you might have to change your
tune point on the primary by about 1/10 of a turn...
