This is just a very short video showing the importance of a variac or dim bulb tester when working on old radios.

  • I thought the idea of using a light bulb, was to actually "siphon off" power from the short, like a varistor...

  • Great video and demo, George.

    I've always been a meter-reader guy. The dim bulb stuff freaks me out. I keep picturing the bulb exploding in my face.

    Looking forward to the next one, my friend.

    Regards,

    John
