For fusing I convert all my radios over to standard ATC fuses. The fuse holders are readily available at auto parts as well as replacement fuses. Glass fuses are getting hard to find and I've never been impressed with how the fuse holders go together.?
I'm still using my factory cable for the TX-500 but I'm almost finished building a replacement cable with ATC fuse holder that will become my primary for this rig.
