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.
