On The Bench: Capacitors
Some capacitors sound better than others and I''ve been recommended these special audio capacitors that are made on the forge of Zeus!" Well yes… and no, and maybe. Like many of these audiophile perspectives, there''s a touch of science and a mountain of mysticism involved here.
Maintaining a phono preamp over time
With op-amps the critical things are that you want a low-noise op-amp and you should use precision (1% tolerance) in the feedback circuit, which determines gain and RIAA EQ compliance. You also need a low-noise power supply and/or additional power supply regulation.

What does a capacitor do?
My question will sound really basic and simple, but I have never clearly understood what a capacitor does. I know that it is supposed to store energy, but I never understood its purpose in a circuit. I would love a clear explanation (not …
Op-amp decoupling
Hi folks. I was wondering if there''s any definitive rule on which approach is best in regards to op-amp bypasses: a single 100nF cap across the + and - pins, OR a 100nF cap from + to ground, and another from - to ground? I have read so many conflicting opinions on this over the past month I...
