Capacitors are passive devices that are used in almost all electrical circuits for rectification, coupling and tuning. Also known as condensers, a capacitor is simply two electrical conductors separated by an insulating layer called a dielectric. The conductors are usually thin layers of aluminum foil, while the dielectric can be made up of many materials including paper, mylar, polypropylene, ceramic, mica, and even air. Electrolytic capacitors have a dielectric of aluminum oxide which is formed through the application of voltage after the capacitor is assembled. Characteristics of different capacitors are determined by not only the material used for the conductors and dielectric, but also by the thickness and physical spacing of the components.
Capacitor - F&T, Multi-Section, Electrolytic
High quality multi-section can capacitors from F&T. These capacitors are similar to the LCR caps found in many Marshall and Hiwatt amplifiers. The body has a 1-⅜" diameter and a 2" length. A 1-⅜" mounting clamp is required. Made in Germany.
Starting at $10.95
Capacitor - JJ Electronics, 500V, 32/32μF, Electrolytic
Same diameter as LCR. Great for use in Marshall amplifiers. 1-3/8" dia. x 2" long
Capacitor - 500V, 32/32µF, Electrolytic
This low ripple capacitor tests superior to any other capacitor of its value currently being made. Commonly used as filter capacitors in guitar amps. 32μF + 32μF @ 500VDC. 1-3/8" dia. x 2" tall. Requires clamp - S-H122. Replacement for LCR. The common negative terminal is dotted.
