Default Just bought some of those Russian paper/oil caps off of ebay

I just bought some of those Russian paper/oil caps off of ebay. I haven't had a chance to try them out yet, but If anyne was wondering, I did give them the 'ol magnet test, and the leads and housing are non-magnetic. So that bodes well for their non-inductiveness.... uh, non-inductivity... um, non-inductivication...

Which Russian PIOs? The green version? The K40Y-9 body is solid steel and very magnetic, as are the crimps where the copper leads enter. Fortunately the external case is supposedly wrapped around a glass inner sleeve which isolates it from the cap internals. Curious which model you bought.

Uh... dunno which odel as I can't read russian, but the mody is most definately aluminum, and the leads are most definately non magnetic.

Thanks aletheian, not familiar with those. The K40Y-9 looks like this, available from QRO Team among others. Who sells the type you bought?

Gintas at KW Tubes in Lithuania. I don't think he has any posted right now, but he has been having server problems, so maybe he just took them all down for now. They were labeled as "aluminum bodied paper capacitors", I can't find any info on the particulars of the dielectric... I am assuming paper/alum foil, but I don't know about the oil part. The only designations on the box are OXO 462 149 TY, and then OTK-2-105 down at the bottom. I dunno, OXO is a mineral acid of some sort, so I guess that is the oil, unless X translates to something else in Russian. I'd pop one open, but I'm afraid that it might contain PCB's, so I don't want to rusk it.... I mean risk it... Freudian slip there
