Need electrolytic cap suggestion, 10uf

I want to replace the 10uf coupling caps in one of my amps. Since Black Gates N series 10uf's appear to be unobtainium, what would be the next best thing?

I'd LOVE to use Sonic Caps, Mundorf S/O, or Clarity MR's, but I don't believe I'd be able to fit anything larger than a 1.5uf Sonic Cap in it's place.

Thanks,
Mike

    Are they at the input?

    10uf WIMA MKP4's polyprops might fit as might the Panasonic ECQ Polyesters.I have used both types for coupling in preamps.

    Thanks!

    Yes, it's in the input.

    The Wima appears to be about .75 x 1 x 1.5, it might work. I'm not familiar with polyester caps or the sound from them.

    Your welcome
    Yes, it's in the input.
    If thats the case then depending on the actual input impedance a smaller value cap could be used without sacrificing bass response. With input impedances in the 47k -100k range anything over 1uf should be fine.
    I'm not familiar with polyester caps or the sound from them.
    The Panny ECQ's are the caps Nelson Pass suggested for use in the Bride of Zen DIY pre I built a few years back.Inexpensive and IMO very transparent.

    Input impedance is only 20k. And if it matters, I'm using a passive pre.

    With a 20k ip I would use atleast 2.2uf.The passive pre won't be a factor as far as the caps value is concerned.
