Jupiter Vintage Tone Astron/Sprague Style Film and Foil Coupling Capacitors

Jupiter Vintage Tone Astron/Sprague Style Film and Foil Coupling Capacitors

Made in USA
Same construction as the Astrons used in tweed Fenders, the blue Spragues used in blackface Fenders, and the Sprague Bumblebees, Black Beauties and 160Ps used in vintage amplifiers and vintage Les Pauls. Top choice for correct vintage tone in repair of 50s and 60s amplifiers and new builds of vintage-style amplifiers.
Also an excellent choice for Gibson and Fender guitar tone circuits. .01 uF value coming soon for 18 Watt and VOX aficionados.
These capacitors require several hours of break in time to form, and sound their sweetest.

Jupiter Beeswax-Paper-Foil Capacitors

Jupiter Beeswax-Paper-Foil Capacitors

Made in USA
Jupiter Condenser Co. Beeswax-Paper-Foil capacitors are precision-wound using only the finest USA materials. The Beeswax-Paper-Foil is a high quality paper capacitor, with the warm tone and richness characteristic of paper capacitors, but with greater clarity, detail, and sweetness. Like good audio speakers, high end caps such as Jupiter Capacitors require a break-in period. Initially, there may seem to be frequency imbalances and other unpleasant characteristics. This will gradually work itself out while playing the capacitors, and the tone will sweeten.

Jupiter Beeswax-Paper-Foil Capacitors, High Temperature

Jupiter Beeswax-Paper-Foil Capacitors, High Temperature

Made in USA
These caps are the same as the Beeswax Capacitors, but made for higher temperature applications such as power amplifiers. Like good audio speakers, high end caps such as Jupiter Capacitors require a break-in period. Initially, there may seem to be frequency imbalances and other unpleasant characteristics. This will gradually work itself out while playing the capacitors, and the tone will sweeten.

Fender Groove Tube GT-6L6GE, Duet

Fender Groove Tube GT-6L6GE, Duet

The Fender® GT-6L6GE is a reproduction of the original General Electric clear top tube. All Fender® Tube Amps come factory-equipped with Groove Tubes; they are much easier to replace (no re-biasing needed when replaced with color coded sets). They have improved harmonic balance, longer lifespan, matched gain to distortion ratio, plus a wider frequency response.

JJ 6V6, Matched Pair

JJ 6V6, Matched Pair

Fantastic sounding 6V6s. Probably the "chimiest" of the new production 6V6s, and certainly the most reliable. These tubes can easily handle the higher voltages of Deluxe Reverbs, Princeton Reverbs and other amplifiers with higher plate voltages. Sound great in Tweed Deluxes and other 6V6 amps as well.

The Soul of Tone - 60 Years of Fender® Amps

By Tom Wheeler, Foreword by Keith Richards
Wheeler chronicles the entire history and evolution of "The Other Legacy of Leo Fender," leaving no knob unturned, with extensive commentary from those who’ve designed, built, marketed and played through Fender amps ever since their humble post-war beginnings in a Southern California radio shop right on through to today. The book contains hundreds of black-and-white and color photos of amps, artists and artisans. An entertaining read and an invaluable reference work.
Includes two audio CDs featuring various vintage and modern Fender amp sounds, as produced by guitarist extraordinaire Greg Koch and Fender’s own John Dreyer, Ritchie Fliegler, Steve Grom, Mike Lewis, Richard McDonald and Nicholas.
