Yazaki-san on Jupiter Comet Aluminum Foil Hermetic
Audio Capacitor
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

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.
