Description

The vintage Russian K40Y-9 capacitors in this precisely matched pair are high quality PIO (Paper in Oil) types made for the Soviet military. They have glass-sealed aluminum foil conductors and oil saturated paper dielectrics in a metal bodies--similar in construction and performance to the more expensive Sprague Vitamin Q capacitors. Great for improving guitar tone or for use in high-end audio applications. These capacitors are unused, straight from the factory packaging. They have been checked on two capacitance testers and then run in a custom fixture to check for leakage at full rated voltage. They are matched to within 1% of each other and within 5% of the rated capacitance. Dimensions (each): length = 23mm | diameter = 10mm
