The grooves on a record contain all the information of every kind of music from rock and roll to classical, but how does that work? How can a series of wiggles translate into the London Philharmonic Orchestra?

The trend in electronics today leans towards inclusion of a switch mode power supply as opposed to the more traditional toroidal analog supplies. Is this a good trend and how do they work?

This audiophile doesn’t like the way traditional potentiometers sound in his system and wants to copy what we do in the BHK preamplifier. How does it work?
