about 1/4 inch thick.
It was a monster.

He then drilled holes (I'll pick a number) "3mm" in diameter into every
A typical banana plug would fit snugly into these holes.
Thus you were able to tap anywhere you wanted, just as Jerry suggested,
using clips.

These things had about as close to zero loss as you could have.

Would make a lot of sense using a circuit based on the K1JJ design. 

Measure the correct diameter of the banana plug.  My "3mm" was just an
