[sdiy] emulating bi-polar capacitors

[Mike Bryant]

>I've never bothered, I've never noticed a difference in just using a 47μ instead of playing about with back-to-back capacitors even after the thick end of 40 years the earliest stuff I built that way still has capacitors that capacitate just fine.

Agreed.  Unless you actually have a reverse DC bias voltage (in which case rotate the capacitor) I've never understood any need for the non-polarised capacitors.  Most mixing consoles are full of thousands of them either feeding the input or fed from the output of an opamp via a resistor to ground.
