Jupiter Comet Silver foil Series
Paper in oil capacitors


Silver foil recreates a great sense of space, recording height, width and depth are very much more apparent with a great sense of ease and a powerful flow. Weight and dynamics are expressed effortlessly, musical air fills the room like no other capacitor. Jupiter Silver Foil types are the most musical capacitors available at any price.

Comet Capacitors feature true hermetically sealed cases with mineral oil impregnation construction that dates back to the 1940's.

Mineral Oil delivers more transparency and dynamics than Vitamin-Q type, with deeper and tighter bass accompanied by a more vivid presentation.

Jupiter Paper in Mineral oil.

Paper in oil construction is one of the original and most reliable oil types. Jupiter uses the finest quality highly refined USP-grade mineral oils. Hermetically Sealed and processed under a deep vacuum for several days. Hermetic sealing keeps oil from leaking out and provides protection from ingress of moisture to ensure long life.
Glass to metal end seals are soldered into tin-plated brass tubes to form leak-tight joints. Jupiter Silver Foil Comet capacitors are built to Mil-Spec standards yet developed and refined for sonic perfection.

Application Notes:

For best results keep capacitors as cool as possible, use common sense. Do not place next to or touching hot resistors or under-chassis signal tubes that get hot etc. This is good practice to follow with any capacitors, especially paper capacitors. Generally for every 10 degree C increase, component life is diminished by half.
