It has been a long time since I worked in the industry, but I seem to recall that the values marked on the caps is in "MICROFARADS," when not marked otherwise.

In the "old" days we used a benchtop AC powered "IMPEDENCE BRIDGE" to characterize the value of caps. I think I remember reading somewhere that there is now a battery powered, handheld device called an "LCR METER," which does the same thing.

I checked with a couple of my local Radio Shack stores, and they don't even know what an impedence bridge is, let alone an LCR meter so if you want to get one, you'll have to go to an electronics supply house used by professionals.

Another possibility for characterizing the values is to take the caps to a local TV/electronics repair shop and a technician might be able to help. Another possible source for help may be a local "Ham" radio club, or an operator.
