Copper foil paper and wax capacitors.
Condenser Co. Copper Foil capacitors are a large plate
area cap specifically designed for audio applications.
Each capacitor is precision wound of the finest USA
materials and is carefully constructed entirely by expert
We believe the dielectric is the first area to be addressed
in capacitor manufacture. Since the early 1900's to
the late 1940's paper capacitor research was focused
in the area of dielectrics, there was no mention to
foils. Paper formulation and it's handling were key,
though impregnants were considered fundamental and anti-oxidant
characteristics of impregnants were prized. Thus we
began our research on improving impregnants first, then
improving the properties of the paper itself. Beeswax
naturally contains small amounts of propolis, which
is a very powerful anti-oxidant, other properties include:
anti-bacterial, anti-fungal, and anti-viral. Propolis
protects the paper and foil from oxidation and degradation.
caps are designed for use in high quality high definition
audio signal circuits. From tube gear to solid state,
more users can enjoy the benefits of their natural high
The "new look" to Jupiter Condenser Co. capacitors,
is true to form following function. Not just a new style,
the outer casing is still true to natural materials
yet offers improved environmental characteristics. A
paper tube impregnated with phenolic resin assures excellent
moisture resistance along with a resin end fill to lock
moisture out. The casing material will not melt or drip
even at higher temperatures.
capacitor section processing...... a refined impregnation
system* is utilized, capable of deep vacuum and high
pressure. Vacuum pressures well below 10 millitorr are
achieved, and even higher positive pressures assure
consistent impregnation with more gas and moisture removal.
New proprietary measures of strengthening dielectric
properties have been developed and employed which yield
higher insulation resistance and allow greater operating
temperatures. Wax and paper construction yields a very
well mechanically damped capacitor, free from electrostatic
and mechanical ringing.
computer controlled wax vacuum impregnation system was
engineered and built by Jupiter Condenser, and section
processing is based on techniques developed by Western
Electric and RCA.

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.
