Sprague Atom Electrolytics

The Sprague Atom series is are legendary electrolytic capacitor made by Sprague (now under Vishay/Sprague). They’ve been a long-time standard in guitar amplifiers, vintage audio gear, and hi-fi equipment, especially for filter and power supply sections.

Well-known in tube amps – used in Fender, Marshall, Ampeg, and many boutique builds for decades.
Axial lead design – leads extend from opposite ends, making them ideal for point-to-point wiring in amps.
High reliability – designed to withstand high voltages (up to 600V, depending on model).
Large physical size – Atoms are much bigger than modern equivalents of the same rating, which many builders believe helps with heat dissipation and durability.
Tonal reputation – some musicians and amp techs feel Atoms impart a classic, warm, vintage character, though others argue they are electrically neutral compared to modern caps.
Still available but expensive – due to demand, they often cost more than alternatives like F&T or JJ Electronics capacitors.
