.022uf/400v K40Y-9B - New Old Stock Russian - Paper in Oil - B

New Old Stock K40Y-9B Soviet military paper in oil (PIO) capacitor - .022uf/400v.  This is the B version which has the non-conductive coating on the case.

The K40Y-9 are high quality PIO capacitors made for Russian military.  The conductor is made of aluminum foil and the dielectric is oil saturated paper, glass sealed in a metal body.  These capacitors provide excellent sonic characteristics, and a high tolerance within a wide temperature range.  022 is common value in Les Pauls, SG's ES Series, Epiphones, even some newer Fenders.  Super nice cap.  These are getting harder and harder to find.
