◆ When used with high-quality oil block capacitors, the sound is well-balanced, natural, and has a refreshing high-mid range extension. Ideal for tube audio amplifiers. The actual measured capacitance is 36μF. DC 630V / AC 450V ● The polarity of the applied voltage for high-quality sound is also indicated during listening tests (red/black). This is a cut above ordinary electrolytic capacitors. ◆ Please note that the appearance is a used item, so there may be scratches and slight dents. ◆ Size: Metal fitting circular outer diameter 60φ H90mm
