Is this a film cap Stan?
Sounds good huh?

Looks like polyester to me, looking at the yellow colour. It's rare to get them in 10uF size at this price. Worth a punt.

If I have to slightly open up the PCB holes, I'll destroy the through-hole plating and will have to be careful to solder them both sided.

Martin, the problem with loosing the plating holes is a bit taxing, theres not a lot of track to solder too if it all goes.

Cheers Andy

I'll take a look at it later, Andy. The alternative would be to solder some thinner wire to the ends of the cap cables and then solder those into the PCB, or to thin out the cap cables (stranded) and solder only half in. I think I prefer the latter.

Certainly worth trying, the only other compact films I've seen are these http://gb.mouser.com/ProductDetail/W...km8IK5PCzWaA==

I wouldn't call the one on eBay compact

. But thanks for that Mouser info. I saw a couple of genuine compact ones worth trying.

Thanks Stan, ordered two, worth a punt as you say.
(I see someone else has bought 16....hmnnn

The AuriCaps won the day. I've now soldered in the 2.2uF 200V AuriCaps in place of the 5-way socket. I did it this way as I wanted to retain the protection of the muting relay. I took care to have the signal input flow into the black leads and output from the red leads, as advised in the Audience application notes.

The PCB holes had to be opened up and I did this with a needle file as I didn't have the correct diameter drill. No worries about through-hole plating as this (front) PCB is single-sided. the caps are held lightly in place with small foam sticky pads to prevent them from vibrating.

The AuriCaps sound fantastic: highly transparent, deep and tight bass, wide soundstage. I am well pleased with my Caiman and use it every day with Sky HD and Blu-ray inputs. I don't intend opening it up again for a long time

Aren't you going to try the wire link instead of the resistor behind the 5V murata reg then?
