Power Cables


Is it necessary to use the same brand and model of power cables for the amp and pre-amp? Any thoughts about mixing and matching? I know it all comes down to how they sound, but would love to hear your inputs or tips to guide me in the selection.

I remembered seeing that cartoon somewhere, so I looked it up. It is good to "Lighten-Up" when one gets too serious, isn't it?

A full-wave rectifier uses both halves ot the 60Hz input flipping the negative phase of the sine wave to create a 120Hz positive-going input to the power supply filter capacitors.
* These are not square pulses with high harmonic content though.

Darn it! I wish I knew how to post a image directly!

Oh! Vacuum tube rectifiers like 5U4/ 5AR4 are full-wave.
