About
Electronics Old & New
As an electronics engineer that finally returned to this field for fun, I like to restore old tube radios and tinker with just about anything in the field of electronics that takes my fancy. It generally includes some audio application, but that is not a rule. Tube radios, guitar amps and effects pedals, audio amps and speakers, and even Ardiuno projects have served to keep me at my workbench until all hours and out of trouble.
This channel serves as a personal video log of some of the projects that come to life (or not), and to share it with any other aficionados out there who suffer from the same ailment.
