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

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

I have popped a few Synergistic fuses but now realize I have to go up a number, from Large 2A to 2.5. I think the Purple Fuse is the greatest value in audio performance, almost equivalent to upgrading IC's or PC's. Only fuse is accessible in my VTL 7.5 iii pre, and my Sansui TU-1X tuner. The pre did marvels. Will similar improvement work on the Sansui tuner, ca. 1977? Thx. Neal
