Beeswax-Paper-Foil
Capacitors)
Jupiter
Condenser Co. Beeswax-Paper-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 hands.
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.
Achieved results of the Beeswax-Paper-Foil are
a reliable paper capacitor, with the warm tone
and richness characteristic of paper capacitors,
yet has greater clarity, detail, clarity, and
sweetness. Attention paid to all details makes
this a special product.
Features:
Hand
soldered leads.
Extended foil construction, soldered across
foils for lowest inductance.
Very low inductance.
Precision winding machines: wound even and uniform
with precise tension
Greater low-level charge and discharge due to
large plate area.
Anti-MDI: No plastics are used in construction.

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.
Again,
do not place in close proximity of hot resistors,
hot tubes, or anything else that gets hot.
Cautions
when using in a pentode circuit: The higher
the grid resistance used, the greater the reduction
of the insulation resistance will occur.
DO
NOT USE IN POWER SUPPLIES NOR BY PASS IN POWER
SUPPLIES! (Special power supply caps will be
available soon.)
