Now Available Auricap Film Capacitors Auricap .... considered by many Audiophiles as "the best capacitor money can buy". Construction: Auricaps are made in USA with the very best precision wound metalized polypropylene film with extended foil (non-inductive) construction. Special care is taken to insure industry leading ESR values. Applications: High end Audiophile uses include: signal coupling, loudspeaker crossover apps, power supply decoupling, filtering, bypassing and power factor correction applications. If you are restoring vintage tube radios ... absolutely no need to use these audiophile capacitors. Our other lines of film capacitors are ideal for tube radios and are way more economical than audiophile capacitors. Specs: Auricap Specifications Auricap Prices & Shopping Cart	In addition to the traditional Auricap audiophile capacitor (pictured at left) and its successor the Auricap XO, we carry the unique R version where solid tinned copper leads exit from the "periphery" of the Auricap body (as pictured above). Leads: Auricap and Auricap XO use "stranded" hookup leads. Auricap leads are made of polished, stranded High Purity Oxygen Free Copper with XLPE insulation while Auricap XO use insulated OHNO mono crystal leads. The R version uses "solid" tinned copper leads. Although some people refer to the R version as radial, they are actually tubular (same body as Auricap) but with solid leads and unique lead position which makes the R version ideal for circuit board and/or hand wired applications. We provide free black and red heat-shrink with these unique R version Auricap capacitors.
