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

I know nothing about this particular amp, but it's very common to mute the output of a preamp using relays while it is powered on (to prevent a loud thump going to the speakers).
It sounds like this is malfunctioning, as sugarbrie suggested. I doubt if changing valves would help.
