I know the problem, that $20 TMC GPR-90 I got at a garage sale back in August just sits there, the part of the fuseholder that screws in missing, I suspect I lost it on the way home (by bus, and walking along putting it down every so often). I thought for sure I had plenty of the caps, but an immediate search turned up none, and I haven't gotten around to looking in the basement boxes. Of course, the rectifier tube is mechanically unsound, so I need to dig the box of tubes out too. Michael |

"Michael Black" **Install a new fuseholder. No, he just needs the part that screws in. I thought all of those were standard. ** ROTFLMAO !! Fuse holder caps have NO standardisation !!! There are literally many hundreds of incompatible designs. A missing fuse cap means replacing the holder, in 99% of cases. ..... Phil |

Yes! There! Ok, so what I'm having to do is use a bolt that the fuse end sits in, and using electrical,tape to hold it in the fuse holder. I'll be damned... Everything works! Granted, some of the knobs need to be fixed a bit and I should probably calibrate it, but IT WORKS!
http://i.imgur.com/6wdKZvM.jpg Now I just need a probe and some alligator clips! You guys have been really helpful, even if it may not seem so... I may end up replacing the fuse housing, but I really don't feel like I need to at the moment Thanks again! |
