Phono pre-amp problems


Hello to all,
I have Sonic Frontiers SFP-1 signature phono stage and wondering if anyone has had this problem with this phono stage. The problem is that when playing an LP the sound will go out and no music will play for approx. 2-3 seconds, then back on, it will do this three or four times in a half hour and I hear a clicking noise inside the phono stage, It's the same clicking I hear when unit is first turned on and when it's warmed up. Every time this happens the led light blinks on the phono stage as if I were turning it on. Anyone care to tackle this one?
Thanks

Yes. Bad tube can cause this type of problem. If one of tube has a short, it is possible that LED might go off and blow the fuse.
Jsawhitlock, now that you have explained it better, I believe your mute circuit has problem. I never had SF product so I don't know how it is designed. If there is a bad relay for the mute circuit, please go ahead and replace it.
