WELCOME TO

KEN'S HOBBY ELECTRONICS PAGE

Model railroading electronics that stand the test of time. I've produced some of these designs since 1990 and continue to receive praise from my customers, both new and old. These are all original designs and are completely manufactured right here, not in Asia. Never have been, never will be! I'm not going away anytime soon and will continue to support both my products and customers with the extraordinary service and high quality products that they have come to expect from me over the many years I have been producing these items.

New for 2016 - The BD3B block detector circuit supercedes the BD3A. No change in size, operation, or installation. Just some different part numbers and fewer components.

NEW - All my instruction sets have been converted to PDF for downloading. The whole index page is less "busy" now with better access to information.

My audio products have been re-located to my new vacuum tube audio products web site at http://www.classixaudio.com
