Re: 3 blown Power supply's in 6 months.

Fuses in that radio would be required by the UL so that it
does not kill someone. If fuses are routinely blowing, then
fuses are too small - nuisance tripping. That too
demonstrated in another post with numbers.

To protect electronics, a fuse must blow in microseconds.
But again, you damn the numbers. You know better because
undersized fuses in a Radio are nuisance tripping. That alone
is sufficient proof of what? Next you will claim a UPS
provides protection that even its manufacturer does not
claim. Why? Your speculation, as ususal, is proof enough.
Numbers be damned.

For others, numbers are provided elsewhere. Fuse takes
numerous seconds or minutes to protect from an overload. But
after damage has occurred, the higher current will quickly
open the fuse - to protect human life.
