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.

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.
I'm using the same caps right now k42's i think is whats on the label. I give them a thumbs up for sure.
PRNDL, beleive theze k42 definitly dznt proper for sound.
But, if you want enjoy music during atomic war - thats right cups. 🙂

Theese Ê42-Ó2 are without any oil, simplifying the sound, not best choice for amplifier.
They were discussed at our russian forum "Audioportal".

For hifi use get some of the FT-3 metal cased Russian teflon ones instead, they're stunning. Most of the ex military stock, tubes, sockets, and caps I have purchased on eBay have been at least "pretty" good and are very inexpensive compared to comparable parts made here.
I have purchased caps and tubes from eBay vendors, sometimes repeatedly:
alexer1
kievfilarmony
and can unhesitatingly recommend them.

edit:
For guitar amp use those paper caps might be just the ticket, you'll have try them to see what effect they have on tone..

I'm considering the K72P-6 .018µF teflon caps for my octal champ, to give it a glassy tweed tone.
The price is fantastic!

Yikes, what a scrambled mess of a post. Teaches me to not type during conference calls. Sorry about butchering your name Kevin, and I meant the K72P-6! Incidentally, for small values the FT-1 is terrific, all non-magentic construction and apparently copper leads. The 5.6nF works a pip in a Scott LT-110B at IF and lower frequencies.
I was thinking about these as closest to .022 and .047:
.022uF 400V PIO K40Y-9.
.018uF 500V teflon K72P-6
.033uF 400V PIO K40Y-9.
.033uF 500V teflon K72P-6
I was thinking it might be cool to do a "Capacitor Shootout" and compare them to yellow Mallory caps in a guitar amp.
.022uF 400V PIO K40Y-9.
.018uF 500V teflon K72P-6

Definitely worth doing imho, but make sure you compare to them to the same value mallory caps to avoid tonal shifts due to different -3dB LF cutoffs. Wouldn't hurt to value match them on a capacitance meter. Probably a no brainer.. 😀

I think we all have those moments.. 😀
I'll check out the FT-1 when I need to order some small value caps. I need to start looking for some better caps for the passive riaa equalizer in my phono stage. I'm always amazed at the low prices these go for relative to comparable western caps, and I suspect they are far better than the ubiquitous bumble bees some people still love..
