Hello all,
I'm having the hardest time finding a good audio electrolytic capacitor model. I have tried all the usual suspects, mouser/digikey/allied, plus ebay and amazon. The only ones that meet my criterion are cheap no name chinese (see pic for a possible candidate). Apart from that the ones I found that seemed highest quality were Rubycon PX at Digikey's, and they look rather ordinary to me.
The specs I have are strict, as it is for re-capping a rather old amp ('90s), and the case is crammed so even the size matters ;-) The application is power supply filter caps, a single cell after the rectifiers. The supply is feeding a regulator, so being "audio grade" might not be necessary in this position but if the extra cost is not too high why not. I am re-capping because the caps there are 30 years old, not because I fall for the re-capping frenzy we see too often in audio. Original parts make is "Eurocap", it doesn't seem to exist anymore.
The specs are 2200uF, 63V, 105°C, axial but not snap-in, max diameter 18 mm, max height 36 mm. Lead pitch is 5mm on board but different pitch can be acceptable with a bit of lead forming. Apart from pitch all other parameters need to be exact. Low ESR would be nice but the ones currently in the amp are not marked as such, I believe it's not critical to the application.
Can anyone recommend a good source? Otherwise I'll go with the chinese, I'm a bit curious to see if the sound would be affected at all. After all technology has evolved since the last century lol
But since I'm doing this I might as well *try* to see what's the best reasonable option. I will *not* pay 50$ a piece.
Thanks!
Joris
