We have discontinued sales of a number of infrequently ordered and obsolete components.

Items such as transistors, coaxial cable and other small parts are changing in price so frequently that we are unable to maintain stock of such items and offer them to our customers at reasonable prices. We apologize for this inconvenience. Most of these items re readily available from commercial electronic parts suppliers such as DigiKey, Mouser, Arrow, Newark, RS Electronics. Other miscellaneous items and coaxial cable are available on eBay and other second source outlets.
