I'm sure he does, but it seems you don't. The 75 or 50 Ohms is
nothing to do with resistance. It's the impedance seen by the
wavefront as it travels down the cable, and is a function of the
inductance and capacitance of each tiny segment of cable. (Calculus
and all that!)


What is the unit of impedance?

What is the characteristic impedance of "any old piece of crap phono leed".


As the old saying goes: A little learning etc..


Try a little reading.

True, I hadn't looked far enough back up the thread.
