Capacitor help
#1 Capacitor help
Hi all,
I am trying to source some 4.7uf 63v capacitors. They are for a Jolida JD9 phonostage. I would prefer polypropylene but I can't find any anywhere. Don't this value come in polypropylene???
If not, what's the next best thing?
Thanks in advance.

Whats it for in the phonostage
Depending on the use, budget and the space you have, there are dozens here.

It's the coupling caps(?) Between the opamp stages. They a polyester (?) Currently. I'm not 100% sure of the technical terms lol.

There is such a wide range available, the cost of some might make your eyes water.
I'd suggest the Mundorf Mcap supreme as a very good, but not absurdly expensive capacitor. Don't worry too much about the voltage rating.
Hi-fi Collective is your friend for upgraded amp components.

+1 for Hi Fi Collective. The ClarityCaps are nice and affordable.

#6 Re: Capacitor help
Cheers guys, I currently have Mundorfs Supremes in and they are very good. Clarity caps are on the to do list though.
The Caps I want to replace are inbetween the three opamp stage (8 total) they need to be quite similar in size, about 18mm wide and quite squat. It's a bit difficult to find something similar. The one Nick linked earlier is too big which is a shame.

#7 Re: Capacitor help
With that size restriction, I would stay with the orange drops, they are not bad.

#8 Re: Capacitor help
Thanks again, Nick. I appreciate your input.
It's going to be difficult, if not impossible to find anything to fit in that restrictive space
Damn.
Is there anything better?

#9 Re: Capacitor help
You might just find these are better ( not expensive either ) used as a pair, nose to tail.

They are non-polar.
You could use two 2.2u/50v or two 4.7u/50v if the value is not critical.
I used a pair like this , 1uF , on input to a chip amp - seem pretty transparent.

Whats the point of using them nose to tail given they are bipolar?

#11 Re: Capacitor help
Wasn't it something to do with the distortion level being lower due to some aspects of the construction being balanced-out if paired that way ?
Didn't we discuss this in relation to how to find replacements for Black Gates ?
...obviously not !
In that case it came only from that thread about the TDA7297 mods, and I'm not sure who came up with the recommendation.
That's what Audio Note used to do with the NX and NH ones though.

May be right, I was asking not saying.

Somebody should try it both ways .... Bigman ?
