replacing some caps

Why were you replacing them? The red caps look like they may be rebranded Wimas, which would already be fairly ideal in the space provided. If you get boutique film caps to replace them, the form factor is going to be cylindrical and larger, which would be difficult to fit.

Replace those big power supply caps with some

Nichicons (or similar good quality) rated for power

supply use. Look at the ripple current spec.

Higher is better. You can use a larger capacitance

value as well as long as it still fits. Re-solder the wires

just like they were before. I wouldn't bother to replace

the red and blue film caps, they look pretty good already.

I also noticed some op amps in there. You might be able

to replace those too with newer, better sounding ones.

Make sure you know what they do before you replace them.

Good luck with it!

I'm not personally familiar with the Rubycon CE's, but generally speaking - I'm not sure replacing those with Nichicon's would be considered an upgrade.  Rubycon makes some of the best capacitors available.  Their only problem is that they don't seem to be distributed very much in this country.  I was sort of hoping that would change now that they're not so tied up making Black Gates.

Sort of wondering if your effort on re-capping is misplaced.  It looks like you have a very modern complement of caps.  It's not like there are a bunch of paper electrolytics or wax caps in there just waiting to fail.  In fact, seems like I see a bunch of Muse ES's and FG's in those smaller electrolytics.  Those are pretty much state-of-the-art today. 

I think he has already replaced many of the caps...those are the ones you are seeing.

I tried to find some data on the Rubycon CE but I guess they have been out of production

for too long, i came up dry...

I wouldn't feel comfortable saying yes unless I knew what the function of the cap was...

If it is just a filter then you would be safe.

If the op amps are in the signal path then they could have a huge effect on the sound.

If they serve some other purpose then just leave them be...

I did that on my sound cards though, i thought that's different? Cheers :) By the way, there's a small cap there behind the 2 black caps, rated 1uF and 160V since i can't find any quality ones at the dealers here with these specs, how safe will i be if i replace it with a 2.2uF or 4.7uF one and higher or same voltage cap? Thanks

If you have an aptitude for electronics you can try and follow the signal path

through the circuit by eye. If you have the service manual or schematic, that

would be a big help.

What amp is it?
