The death of hand wiring

Paul McGowan writes: Printed circuit boards, those thin copper strips laminated to fiberglass, paper, or ceramic plates routing complex electrical signals are common today. It wasn’t always so.

Valve microphonics

J. Evans writes: The construction of a valve is not a completely rigid structure. Any relative movement of the various electrodes not only affect sinter-electrode capacitances but also variations in current and mutualconductance.
