WEET WMH MusiCaps are constructed using separate layers of premium foil and polypropylene films, rather than the vapor deposited metallized film used by most other manufacturers. Film-plus-foil construction requires more costly materials and result in MusiCaps being approximately 100% larger than typical metallized-film capacitors, yet the benefits are immediately discernible.It is with regret that Hovland MusiCap in USA have announced that they are no longer making their Musicap Film and Foil Capacitors as a result of increased production prices and lead times for materials used. WEET WMH Pure Aluminum Foil and Foil Capacitor is the best replacement for it.Winding: Aluminum foil spliced to polypropylene insulation film. (a layer of pure Aluminum foil and a layer of PP film).Separate layers of polypropylene film & conductive foil deliver superiors clarity of reproduction that metalized capacitors can not.Top of the range pure aluminum foil capacitor, High Precise Capacitance ±3%. Very Low Dielectric absorption factor.Very Low Dissipation factor.Very Low ESR.Very Low Inductance
