Jupiter Comet Aluminum foil Series
Paper in oil capacitors


Aluminum Foil Paper-in-Oil delivers the classic sound sought after for decades.

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

Yazaki-san used the Jupiter Comet to improve his Marantz model 7 pre-amplifier.

" The following is my experience, even with my Model 7, which has been improved a lot, when I connected it between “Douk Audio U4” and the power amplifier.
Sorry but I heard clearly the sound lost some of its freshness and lively feeling compared to the direct connection. In the end, I had to make a decision to replace the coupling capacitor of the Model 7’s each stage from Arizona Capacitors to Jupiter Condenser Red Comet, fortunately which resulted in clearer sound quality with rich atmosphere.
Actually, I used Arizona Capacitor, 0.22 MFD, 0.33 MFD and 0.22 MFD, in three places of the Tone Amp section, and each time I replaced one by one, I checked the sound quality and experienced how the veil was lifted gradually, little by little.

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 Comet Foil capacitors are built to Mil-Spec standards yet developed and refined for sonic perfection.

Made in the USA of materials from USA and Germany

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.
