Might measure 34uF, but likely that is not going to actually be usable with 10A of current flow, as likely there is a lot of the foil area burned away from self healing, and thus, if unwound, the films will appear to be mostly small areas of aluminium film, and largeareas with missing or transparent film from self healing. They are not great these days, because the old ones were made conservatively, with thick films of foil as electrode and dielectric, but the modern ones use thinner films, and run them at a much higher stress, so they do fail with time, applied transients of starting, and running hot. I still have a few dating from 1977, near the end of the use of PCB oil, and they are still within spec, just that they are four times the volume of a modern one, and you need 2 in an AC outdoor unit with one for the compressor, and one for the fan. Modern ones will withstand 500V applied when new, after 2 years you apply 500V and can hear the capacitor doing self healing from the degraded dielectric inside them. Environmentally friendly though, the oil filled ones use coconut oil, and the dry ones use epoxy.
