Retro Vintage Type PM Audio Capacitors

Audio-optimized Film Capacitors

Proudly made in the U.S., the Electrocube Type PM Retro series is part of a designated line of capacitors, specially optimized
for the high-end audio industry using design and manufacturing techniques proprietary to Electrocube. Its polyester build creates unique characteristics for high performance and long life. Offered in a wide range of sizes and configurations, the Type PM Retro series results in original vintage tones for guitars and amplifiers preferred by audio engineers in professional, commercial stage and studio use.
