    I visited the Instructables site often . . . it had good projects and more importantly it was easy. No sign-in walls. Did Facebook and Twitter make some demands on you. Now it's only an accident that I see a project. You've improved yourself right out of use-ability. Nice enough???

  • DIY Hi-Fi: Vintage Receiver Repair and Modification

    JoeBeau is Absolutely RightNew audio components are not only poorly constructed, (with inferior parts), but worse still they are poorly designed.

If it were a vintage unit, then there would be a chance to discover the problem . . . but with power disappeering behind the front panel, control every function and feature, it's nearly impossible. The front panel must contain processors, 'logic' circuits, and plenty of pretty Blue lights. [Service Manual=none. closest approximate=written in Hindustandi with sections omitted.
