Sourcing a 15nF capacitor for RIAA in FVP5 style circuit.

[InSides]

The title says it all. I have a phono preamp which seems to be based on the FVP5 schematic, and on the 15nF position, there is a 10% tolerance WIMA.

Would like to replace it with a more adequate capacitor, so was hoping to pick minds on a very good capacitor for that position. Sourcing links would be very welcome.

I was only able to find a 0,015uF Mundorf Gold/Oil, but that one is upwards of 40EUR, and was hoping to explore some other options prior.

Thanks!

From the valve itch thread: Russian k42y teflon available from eBay. They are big though....

Hi Insides ...
would this here be good enough ?!
--- leaves you enough money to buy sufficient pieces to select (pairs) .

wima fkp are good too if you can locate some.....

If you looking for accuracy you could parallel 10 x 150nf this will give you 15nf with much greater accuracy

Parallel 10x1.5nF or series 10x150nF. Parallel 10x150nF is 1.5uF!

Only with 10% tolerances - tighter tolerances would require special orders and larger quantities.

I see AuriCaps come in 0.015uF and have between 0.5% and 2% tolerance - but no one seems to stock them. Looks like I might be stuck with high priced options unless I can get matched Russian PIO's.

Found these:

Lot of 20 K42Y-2 0,015uF

But they don't specify tolerance. Would a lot of 20 be sufficient to discern two matched pairs, or should I go for the lot of 40?

Even if I go for the lot of 40, with shipping, that is still cheaper than a single Mundorf.
