There are plenty of places online where you may buy electronic parts in small quantities from reputable vendors. Digi-Key (with blue LEDs, reasonable prices), Mouser Electronics (fast service, $20 minimum, $5 charge under $20, export orders $100 minimum), Ocean State Electronics (good selection of RF parts, especially air variables and B&W coils), Radiokit (plenty of components), Circuit Specialists Inc (no minimum with check or money order, otherwise $15, good RF collection), and Active Electronics are all places you can buy new or "new and some used" electronic parts from.

The list continues with DC Electronics (good collection of ICs and electronic components), International Components Corporation (capacitors, diodes, ICs, potentiometers, resistors, sockets, transistors), Kelvin Electronics (minimum $20, lots of electronic parts and tools), H & R Company (Herbach and Rademan) (minimum $20, lots of electronic parts and tools), and Jameco (computer parts and electronic components).

New and surplus electronics can be purchased for as little as $10 at All Electronics Corp. or $12 at Alltronics or $15 at American Science and Surplus (formerly JerryCo).

Both Hosfelt Electronics and Marlin P. Jones & Assoc. specialize in selling surplus electronics.

Companies like JAN Crystals, Crystek Corporation, International Crystal Manufacturing Co., Inc., Amidon Associates, Palomar Engineers, and RF PARTS might be approached when specialized components are required.

Wholesale directories are another great resource for finding vendors of electronic parts, where you can then compare costs and specifications before making a final decision.
