[R-390] Line Noise

Sun, 2 May 2004 21:05:00 -0500

Buzz,

The waveform is a classic SCR switching waveform, as from a
cheap light dimmer. If the load is large enough, it doesn't
have to be in your house.

The SCR turns on in the middle of half a line cycle, causing
the maximum very fast increase in voltage across the load.

Glad to hear you could fix it so easily.

Regards,
Bill Hawkins

Listers,
I had a line noise problem that I thought you might be interested in.
