Fairchild BC 549 and BC 559 are small signal transistors like the 2N3904 and 2N3906. Those are the ones you're talking about, right?You might try AER, Carlton-Bates and Hamilton-Avnet. They'll probably have access to the Fairchild part and several suitable replacements and cross-references. Seems like parts guys at distributors have a knack for finding interesting devices, so you might give 'em a try.
