Synergistic Orange and purple fuses popping


 

Synergistic Orange and purple fuses popping


I recently upgraded all my gear with the new Synergistic orange and purple fuses (15 in all) What a difference! My Cary SLP-05 preamp with 8 Vintage Tungsten  6SN7 tubes is having problems with the Orange and Purple Synergistic fuses in the power supply. For some reason when I turn on the preamp amp after warming up the powersupply unit, the 2 power supply fuses pop. So far Synergistic has been gracious and replaced them twice now. I increased  the 2 large slow blow fuses from 1amp to 2amps after asking Cary audio what I should try. I also spoke with Synergistic and they agreed their fuses are sensitive but all the stock fuses I ever used have worked flawlessly. Any body out there with any similar problems and maybe a solution? Any upgraded hi-fi fuses that may be less prone to popping? I think it may be due to a current rush (tube related) when I go from off to on. Help!

Thanks

Very early on one of the first generations of SR fuses popped for me. At that time, it I was recommended to go a value higher than the originals. This was due I think to there Million-volt treatment. I think it weakens them a bit.

Anyway, going forward I always have gone slightly higher in value even today with the new purple versions.

Also, I would go for the slow blow at least for your power supply.

Thanks Ozzy for some helpful tips. I did increase the amps to 2 from 1 on the SR slow blows and they still popped. I 'm waiting to hear back from Cary to see if they condone a higher fuse rating. Not sure what it will take and if I'm pushing things to far. They sure do sound good in all my other componenets. I wonder why the naysayers can't hear any more. Best money snake oil can buy imho.

I blew a blue in my preamp after a few months.  I got an orange and blew it in a new preamp from the same manufacture in a few months.  The orange was two increases over the stock.  

I put back in a common ceramic at the rated value and it has been fine ever since.  My opinion is that the fuses are not stable but lots of people like them, I don't.
