A simple catalog sheet fails to tell the story. You need the full spec
sheet which  CDE at least is very detailed. I dont know about Jap brands,
dont use them since getting real specs is damn near imposssible.

Maybe a coincidence but the large majority of my amp repair cap failures
is Jap brands...take it from there.

Absolutely zero failures with USA Mallory CGS types. None in about 5
years with CDE 381LX series either..made in South Carolina.

Individual ham level responses are  potentially dangerous unless they can
show a full test/histogram .  IOW, "Caveat Emperator".
