HP audio oscillator

[Hairy Harry]

I'd start with a can of "zero mist" or "freeze mist" etc.
I don't know if the newer varieties will fry your lungs or
the ozone layer... I think they are safer these days.

Use the little tube to freeze individual components one
(or one area) at a time. When it suddenly works again... the
problem is nearby !
