Russian paper in oil caps - any good?

PRNDL · 26th September 2007, 02:21 PM

These Russian PIO caps are fairly inexpensive when compared with others, but I'm wondering about quality and tone.

do not even try that drek - they aren't worth of solder wasted on them.........

just send them to me for proper disposal

If i read that right and they are indeed K72, they are teflon rather than PIO. I doubt Zen Mod has the technology to safely dispose of those

Ex-Russian stuff has two main advantages - its cheap, and it don't have no fancy audiofile name.
This stuff is mostly ex military spec so is top flight.
I got some lovely ceramic switches a while back - I didn't thing things were made that well since the time of WW2.

I believe those on the picture are K42, they are the cheaper variant (paper w/o oil?). Probably quite OK.

K40 are the PIO type in metal casing. Rather god PIO. I use those.

K72 are teflon. Expensive. Supposedly very good.

FT-3 are rare and very expensive "fluorplastic" type. Supposedly excellent.

Svein.

Definitely maybe. Though potentially designed for the military I've disassembled enough K72's to become convinced a chunk of what's on the market are seconds and rejects.
