Retro Vintage Type MF Audio Capacitors

Audio-optimized Film Capacitors

The Electrocube Type MF 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. Proudly made in the U.S., it offers original vintage tones for guitars and amplifiers in a variety of sizes and configurations. The Type MF Retro series has unique high performance and long life characteristics with its polyester construction, encased in a metal tube, and then hermetically sealed. Creating an old-style soft sound, audio engineers prefer the Type MF Retro series for authentic tonal values in high-end professional, commercial and stage use.
