Capacitors
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.

Jupiter Condenser 400V Bumblebee capacitors made with aluminum foil paper-in-oil. As one of the earliest construction types, featuring a pure paper/oil construction complete with a true hermetic seal. The tone you crave and love, in the most accurate reproduction.

High quality R82 Series box film capacitors from Kemet. These polyester film capacitors have 5mm lead spacing, a minimum voltage rating of 63VDC, and a tolerance of ±10% or better. The small size, high specifications, and radial mounting makes them an excellent choice for PCB builds of pedals, synthesizer, and other audio equipment. The R82 Series is constructed of metallized polyester film with radial leads of tinned wire. Radial leads are electrically welded to the contact metal layer on the ends of the capacitor winding. The capacitor is encapsulated with thermosetting resin in a box of material meeting the UL 94V–0 requirements.
- Voltage rating: 63 VDC Minimum
- Lead Spacing: 5 mm
- Capacitance tolerance: ±10% or better
- Operating temperature range of -55˚C to +105˚C

Mallory axial capacitors rated for 400V. The available values are smaller in size than the 630V versions for builds where less space is available. These are also a great choice for use as guitar tone capacitors over the larger 630V versions. The Type 150 series axial lead metallized polyester non inductive capacitors are available in bulk or on tape and reel for automatic insertion. Type 150 is a general purpose capacitor for use in blocking, bypass, decoupling, smoothing and some timing applications. Features
- Epoxy end fill meets UL94V-0
- Non inductively wound
- Flame retardant outer wrap meets UL510
- Non polar

Critical loudspeaker crossovers deserve to have a transparent product specific to the application. Speaker MusiCaps, with their thicker leads, are a revelation in well-designed crossover networks. While a fully MusiCap-ed crossover is supreme, just installing MusiCaps in the tweeter circuit will reveal much additional detail and nuance. Many prominent high-end loudspeaker manufacturers have been using MusiCaps in their top models for years.
