Hi Guys,

I can't see why JR has not seen this as a problem.  I have only owned two
JR347's, a JR388 and now a JR8103 and have only blown a fuse one time and
that was when I plugged my power supply for my ALPHA 4 Charger directly into
my 8103 (don't ask).  I was actually kind of pleased there was a fuse in
there to blow rather than toast the whole TX.

See Ya,

Pat McCleave
