RE: Winding primary

Two strings in parallel (such as what I am building) still seems there
is little cross sectional area.  Are you saying that because the leads
are so short they offer almost no resistance like say the ohm per 1000
feet of wire charts would indicate?

thanx

Hi Luke,

The key is those leads are very short and normally in parallel.  The
loss
from the skinny leads is trivial.  They do make those caps with big
strap
leads, but the cost is stunning for the special order...

Cheers,

          Terry
