Russin PIO caps in crossovers?

[David Anderson]

I'm looking to upgrade the 5uF Mylar capacitors (2nd order Butterworth)
in my crossovers, and I've been looking around at the various options.
Unfortunately, it seems that most of the audiophile capacitors in this
range are fairly expensive. I have seen on the web where some Russian
K40Y9 paper in oil capacitors are available in 1uF 200V values at a
reasonable price.

Would it be a good idea to parallel five of these to make one 5uF paper
in oil? I could do my both entire crossovers for the price of one
Hovland 5uF MusiCap.

Thanks,
David

My gawd, how much money are you looking to save?

There are several sources of very good film capacitors of the
capacity and voltage rating you're looking for, check out, for
example, Madisound, Parts Express or Solen. They have very good
caps at reasonable prices.

I would, myself, avoid paper/oil capacitors, for relaibility
sake, if nothing else.

The ones in my Klipschorn crossovers have been going strong for over 35
years now. When should I expect them to fail?
