Electronic component suppliers

Mouser -- probably one of the best parts distributors today for analog-electronics manufacturers -- very broad product range, excellent selection of audio connectors, capacitors, potentiometers, knobs and switches. Accepts small hobbyist orders.

Digi-Key -- very wide range of analog and digital ICs, including exotic types. Mostly specialized toward computer and digital electronics. Accepts small hobbyist orders.

Jameco -- hobbyist-specific distributor, has small ranges of parts needed for analog designs but a very wide range of power supplies. Accepts small hobbyist orders.

Allied -- large industrial distributor, not hobbyist-oriented. Prices tend to be much higher than other firms. Best supplier of Perkin-Elmer Vactrols right now.

Deep Surplus -- excellent low-cost audio and computer cables.
