22nF Styroflex

Parts Questions
1

Hello,

Have anybody got four (or more :>) 22nF Styroflex caps?

I can’t find them anywhere! I was in ~10 shops in Cracow, checked in e-shops where I’ve bought parts, searched on Allegro (polish Ebay ;)) and… found nothing.

Regards,

Lenwe

Hi,

styroflex is simply another name for polystyrene capacitors. Local shops rarely carry them, but a decent online store should have some (Farnell, for example has 22nF polystyrene caps. They’re far from cheap though.)

By the way, if you don’t need a specific type of capacitors, polyester and polypropylene capacitors (they are much more common) will replace them without problem.

Ok, thanks for help. I’ll buy MKT caps tomorrow.

You saw the price tag at Farnell?  ;D

The MKT polyesters will work fine. By the way, polypropylene caps are said to sound better (probably an unnoticeable difference anyways / totally subjective), but they fail after a shorter time, so the polyesters are better.

No, i haven’t. I just know, that MKTs are in shop near my school. Costs around 1,5PLN (1/3 Euro).

About sound differences - is it like audiophile tuning? “Change of power cord to gold one provides deeper low, and cleaner high and better stereo”? ^^

EDIT:

Prices at Farnell:

Polystyrene - €1.69

Polypropylene - €1.51

Polyester - €0.198

Now i know, that polysters are the cheapest ones :stuck_out_tongue:

Pretty much –> BS to sell expensive products.

Deeper low, cleaner highs, better stereo image, depth, etc. This is not the effect of better components but the effect of willing to hear something different. You have to do ABX blind tests to see if there’s really a difference if someone just replaced a component without comparing directly and said it sounds better, then don’t trust it (most audiophile mags, for example).

However, different capacitor types have different characteristics on an oscilloscope, but the difference is so small (you won’t hear it in a blind test) that it doesn’t make a difference.
