[sdiy] NE566 Boon

[Roman Sowa]

That's exactly what happened in the circuit I troubleshooted for a 
friend. It was working fine at 11V and went totally nuts at 15V which 
was in original design.
I stopped at "it works now" stage, telling him to use lower supply and 
never bothered wondering what was the cause.
