Hi,
this reminds me of something that happened many years ago. I had repaired an
amplifier for a friend and was on-air when he first powered it up.
As he hit the "operate" switch I could hear his mother frantically calling
his father in the background, his mother had been preparing something in the
kitchen using a food mixer with electronic speed control, suddenly it ramped
up to full speed and flung the mixing bowl contents up the kitchen walls,
somehow the image of it still amuses me all these years later.
