0.015uF at 75v? So thats 15nF at 75V+. Perhaps the only difficult part would be finding one that fits neatly in the PCB, and perhaps in the enclosure. Not suggesting replacements would be bigger, but its always nice to get one thats a *phyiscal match* as well as electrical.
I'm pretty sure even a ceramic would work, but less than ideal. Its from a radio, but given the 15nF value, I'm not confident its used in tuning so perhaps its type is non-critical. a WIMA at 100V would do just fine I reckon.
