I took apart
my 1982-vintage Nicolette oscilloscope last week. The power supply filter capacitors added up to around 100,000uF, the majority being three 25V 28000uF units on two completely separate linear power supplies. One of the 50V 8800uF capacitors (1.5" x 2.5" approx. ! ) was in such good shape that the guts will rattle when shaken.
haha, that's what happens when a cap. dries out. Still powered up, but I don't think the filtering is what it once was!
This thing was huge. I was thinking you would have room in there for about a case full of modern oscilloscopes that would all beat the pants off this one for capability while being 8x smaller and 30lbs lighter. Crazy.
