The stuff of many peoples dreams. But the prices bring you back to earth.

Not just the prices, look at the size!

"However, my applications usually have several 100V across the capacitor, which is VITALLY important."

"I think that ANY cap works better with lots of DC across it."


In a series looking very deeply at capacitors, published in Electronics World, Cyril Bateman has demonstrated that DC across any type of capacitor always increases distorsion.

Cyril calls your thoughts above myths. They are unfunded technical speculations and speaking of "VITALLY " is intellectually dangerous.

I wrote : "DC across any type of capacitor always increases distorsion."
Read "High DC".

Capacitors distort when there is AC voltage accross them, which means that's when they have a significative impedance at the considered frequency. So it is essentilly in filters and power supplies that they have influence on the sound reproduction.

Let's see.............

2 V AC, and 40 mV DC across a 'lytic in an amp feedback path.

Want to try again?

THel sells EMZ styroflex caps, the square orange dudes.
These are remakes of 1% Siemens KS B31531 styro's.
Used to get the original Siemens in Germany for twice that price, for RIAA applications, and that was wholesale price.
The only good deal you can make at THel's, for anything other it is Th-Hell
