The cap comes from 1983.
It is labelled MFD, they do not mean this. Nowadays it would be labelled μF.
0.013 MFD is likely to be 13nF.
Also they do not mean 4KV, it should be a lower case k.
I do not know where you can find one, perhaps a higher voltage DC cap would do.
Comment The editior transforms k into K when following a number.
