Inspecting a newly acquired HP 2392A I found out the chassis was prone to
whiskering all over the chassis.
Whiskers are small metal hairs growing from pure metal (zinc or tin) and can
when they connect to a power line create a shortage and electric arc
damaging the electronics.
Made some pictures and placed them in:
It's best to remove them by using scotch brite or fine sanding paper, after
that paint or coat the chassis with a clear paint or other nonconducting
