Hi
I begining to dislike these things.
I recently got an old 2090 Nicolet DSO ( Digital scope ).
When I got it, it had a blown tantilum on the 5V
for the I/O section. I fixed this and the blown regulator
along with it.

I bought a Tek 7904 scope on e-pay, a frame-and-4-plugins design. At least
4 of the tants on the power supply were shorted, so I ordered new ones to
replace all the tantalums in the power supply. I think I spent $25 at
Digikey. Works great now.
I thought the caps the leaked on PC motherboards were aluminum
electrolytics. ISTR that some guy defected from the Chinese factory where
they were made and stole the formula for the electrolyte so he could start
up somewhere else, but there were additional chemicals added after the
solution was first made up and his formula didn't tell him anything about
the later steps, so all of his caps failed after various amounts of time
in-circuit.
