When to replace your capacitors?
DavidAlfa:
It depends.
The blue electrolytics in tektronix devices tend to leak, though they're often in spec.
If you detect the usual "armpit smell", that's the electrolyte, though it doesn't always mean it's leaking.

I also thought the display was a bit dim but I have nothing to compare it to. Anyone have a suggested source for replacement VFD modules? I see many on ebay but I generally don't buy components on ebay.

Yes, the digit above the 'Utility' button is the one that remains dark in several measurement modes and settings. Unless you really need more brightness, there's nothing to worry about. This display can last for years, just not with the initial brightness. If it was mine and I needed more brightness, I would not replace this display. Instead, I would try to increase contrast by putting a black cardboard strip above the meter to put the display in shade. Not perfect, but effective and almost for free. AFAIK, buying a good replacement for a reasonable price can be a problem (display is fragile and some sold as replacement have been used for an unspecified time).
