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

Iwin,

Tell me more about those tubes you swapped. What have you tried and how do they compare to something like my vintage Tungsten? I'm interested in how you ended up with the tubes you have. Also now that I have the purple SR fuses I'm breaking them in. What direction did you find sounded best on your Cary preamp? I I have the hot end going in from right to left. Jury is still out on benefits over orange SR.

My Purple Fuse blew after only a few weeks. It uses the same Large, Slow 2A as the previous Orange and Blue fuses, which had no issues. I have advised the retailer and expect they will replace them, but what comfort do I have the next one will repeat? And I really thought the Purple was a major advance.  Neal

It’s interesting that I have only had problems with SR fuses and not any other standard fuse. They were all slow blow and even rated at two levels above the standard. My preamp manufacture cautioned about using a higher rated fuse and I didn’t want to get into a warranty dispute in case I had a problem.

 

Guys,

Synergistic has been quick to respond and replaced any of the fuses I popped at no charge and were willling to work with me to analyze posssible causes. My solution was easy. I turn my Carey SLP-05 preamp on first and then the power supply. The problem we all seem to be having is the current rush when we turn the power supply on. It is apparently a bigger issue with tube equipment. Also our gear could have weakened caps? Since I have replaced all my gear with Orange and now some purple fuses the music has become more real and musical. Improved imaging and detail, etc. The purple are even better. You do have to have good equipment to here major improvements and decent hearing as well. I replaced the fuses on my othe system in FL with the orange fuses but the improvements were not as dramatic. Good equipment there too, but not like my main system here in Chicago. I still wonder whey the cheap fuses never popped?

Glad you got yours figured out, Greg

I had a post last year where I tried the SR Blue in an integrated amp and it blew upon first power up.  The dealer recommended going to a higher-rated but Audio Research did not condone nor recommend this.  There was no problem whatsoever with that amp and this only occurred with the SR fuse.

The current ORANGE30 sale had me considering another go as I have changed electronics to different ARC models now with separates.

I talked to another dealer today, nice lady out in CA, and she said many customers up the values but nonetheless if I want to give it another go at the mfg ratings they are happy to sell and give a full refund if they pop.  This frustrates me that the problem even exists.  Spending $110 each at this point in the game is meaningless....I really wish I could comfortably try them out to let my ears decide if anything happens....oh well.
