Macallan Posted March 11, 2012 Share Posted March 11, 2012 Won't power on. Fuse is blown. Should I just replace the fuse? What would cause a blown fuse? Quote Link to comment Share on other sites More sharing options...
Guest " " Posted March 11, 2012 Share Posted March 11, 2012 blown fuse could be bad tube, accidental short of input or output connectors, over driven, over voltage condition, use of power strips to turn everything on and off instead of the unit's power on button or a sequential soft start device (source on, then, pre, then amp, when powering down, amp off, then pre, then source) Quote Link to comment Share on other sites More sharing options...
Daddy Dee Posted March 11, 2012 Share Posted March 11, 2012 Yep. replace the fuse. No reason for concern unless it continues to blow fuses. Quote Link to comment Share on other sites More sharing options...
Macallan Posted March 12, 2012 Author Share Posted March 12, 2012 Thanks. Should I replace just the fuse or the tubes as well, they are a few years old? Where do I buy fuses? Quote Link to comment Share on other sites More sharing options...
Macallan Posted March 12, 2012 Author Share Posted March 12, 2012 I check Radio Shack on line and they sell them, however they sell lots of variety. Slow burn, fast acting or ceramic and thermal? The Fuse inside the peach has the following on it 312 on one end, 1A/250vp on the other. It looks most like the fast acting fuses on the site but they are all listed by amps. How many Amps? Does the 312 mean anything? Quote Link to comment Share on other sites More sharing options...
Marvel Posted March 12, 2012 Share Posted March 12, 2012 http://www.grainger.com/Grainger/LITTELFUSE-Fuse-2FCG4 The 312 is the series... It's a 1 amp fuse, designated by the 1A. Bruce Quote Link to comment Share on other sites More sharing options...
Macallan Posted March 12, 2012 Author Share Posted March 12, 2012 Thanks. So i need a 1 amp fast blow fuse. Should i replace the rectifier tube as well or just the fuse to start? Quote Link to comment Share on other sites More sharing options...
garymd Posted March 12, 2012 Share Posted March 12, 2012 Thanks. So i need a 1 amp fast blow fuse. Should i replace the rectifier tube as well or just the fuse to start? No. Just replace the fuse. Go to your local RS and get a package of 5 (or whatever quantity they sell). They're only a few bucks. If it continues to blow, then you can begin to worry about why. Sometimes it just happens.

NOSValves Posted March 14, 2012 Share Posted March 14, 2012 Once you have installed a new fuse if it blows the new one then remove the rectifier tube install a new fuse and try it without the rectifier tube. If the fuse survives that then try a new rectifier tube. If it then blows the fuse again it will most likely require a trip back to Mark.
