Hi DIYman



Although polyester caps are good, I wouldn't really recommend them. From all the film caps, they are the lowest quality, but of course still much much better then ceramic or electrolitic.

Ok, back to this topic. I checked with a local electronic distributor and these are, indeed, PLASTIC caps (polyester apparently), and not multilayer. The dielectic/conductor arrangement itself it's microscopic, and beats the heck out of me how they did it but it works. Voltage range is comparably low, 30V.

To my ears they sound as good as any polyprpylene cap i've tried. Down here they're about ar$1,10 each (us$.35 aprox.), and i've already got a few for my preamp!

They look exactly like some ceramics I can buy here. So I'm a little doubtfull of them being polyester, since I've got some 50V 100nF polyesters that are alot larger in size. But hey, if they sound good...

I had the typical "roll" 400v polypropylene stood off the board originally; replaced these in and there's no diference in the sound whatsoever.

Lisandro,

I have advise in the "Everething else" section, in "Sound of capacitors", that Electronics World & Wireless World have initiate a set of articles about distortion in capacitors. In the June issue and next.

Please, read this articles and all your doubts about capacitors are solved.

If you have very low space for a film capacitor, tray with a non-polarized electrolitic, as the Panasonics that can be find in Farnell.

The caracteristics of distortion are best than ceramics. Except NPO.

Your only election in ceramics are the NPO (or COG) have almost the same caracteristics of distortion as the Styroflex (Polyestirene).

Happy days,

Raśl Couto.

If you check out the thread recently titled "Black Gate's Are JUNK" you will find a couple of my posts buried within on the topic of a multilayer ceramic cap sold by Farnell, AVX brand ( I forget the precise detail but I posted them).

These were a 50 volt rated 10uF cap that was about 12.5mm wide, 10mm high and 2mm thick with the leads exiting at the bottom edges as they would in a common greencap.

These babies sound very nice and were recommended by HiFi World magazine a few years back as an often overlooked component with a great sound. I've only used them couple of times and liked what I heard. YMMV
