Title: Capacitor direction
Post by: springcreek on November 23, 2012, 09:17:31 PM

Hi guys
Just got some 1.5uf Obligatto premium caps for the Goodman's crossover today. Any idea if they are directional?
Cheers, Andy

I follow the writing on the cap

I can see a positive + after the name written on the cap but I was unsure if it was indicative as the + was not close to the end of the cap

A + sign ?

I can't remember that on mine, but I bought mine three years ago or more.

The way I install them is with the signal direction the same as the direction you follow when reading the print on the cap.

I guess that follows the same if there is a + after the name :)

You are talking about these ones?

Yep that's them

So neg would be at the end where writing finishes?

Other way....Lettering start end is signal input.

That's how I used them in my ML-1 crossovers, tweeter side.

Nice caps for the $$$

I used the Copper case Obbligato's for the others.

Caps installed over the weekend and my soldering in still bloody awful  :-[

Early days (about 16hrs on them) but they are sounding just as Steven described, rich, smooth, and transparent (just like me - NOT)  ;D

So far only positives  ;D They tamed the slightly aggressive top end on some recordings, which is very welcome

System is now smoother and more organic without losing any weight and magic. I can now listen louder without things getting a little harsh and my ears don't shut down as quick. 8) Happy days

Thanks for the advice guys.  ;D

Original caps were Hunts metallised, which I hadn't come across before.

Now to try out some Neotech copper wiring and replace the Lpad with some good resistors.
