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.
Capacitor - Vishay Roederstein, 250V, 0.68 µF, MKT1813, Axial Lead
High quality 0.68uF axial capacitor rated at 250V. This value is popular for cathode bypass capacitors in many vintage Marshall amps. The 8.5x26.5mm size works well for turret board builds of these classic amplifiers. These MKT1813 capacitors are produced by Vishay Roederstein, formerly known as ERO. These capacitors are made with metalized polyester film and sealed in epoxy resin. Suggested applications include blocking, bypassing, filtering, timing, coupling and decoupling, interference suppression in low voltage applications. Features
- Plastic-wrapped, epoxy resin sealed, flame retardant encapsulation
- Non polar
- Tubular metalized polyester film construction
- ±10% tolerance
- Axial leads
- Operational life greater than 300,000 hours (40 °C/0.5 UR)

Capacitor - Philips, KT-347, 400V, .015uF, Polyester Film
New old stock radial capacitors from Philips with 10mm lead spacing. The KT-347 series capacitors feature the same lacquer coating as the Mullard / Philips mustard caps found in classic Marshall amps and many vintage pedals. These NOS caps feature a low-inductive wound cell of metal foil and a polyethylene terephthalate film.

Capacitor - Mod® Electronics, 600V, Oil Filled, Axial Lead
Mod® Electronics Oil Caps are high quality, hand-crafted capacitors that are the perfect choice for guitars, amplifiers, and all audio equipment. Each capacitor is impregnated with mineral oil for a void-free winding providing highly stable capacitance. The capacitor is hermetically sealed in an aluminum casing to ensure a long life. The detailed construction results in a precise capacitance with a tolerance of ±10%. Mod® Oil Caps also feature a red stripe to designate the outside foil.
Starting at $6.65
Capacitor - 600V, .047µF, Oil-Soaked Polyester
Non-inductive polyester and oil caps, these film capacitors use oil-soaked polyester as di-electric material and are smooth and natural in sound.
