Amp sound occasional momentary cut out


My Integrated Jolida Hybrid 1501RC occasionally has a momentary sound loss/cut out, no volume change just a pause on both channels.  How can I test, trouble shoot a problem like this?  I have tried different sources and inputs.

Thanks for the advice.  Lights stay on, so i'll check the connections.  I may also put back in some older tubes.  I put in new tubes a few months ago. I would guess if it was one tube it would be on one side only. 
Thanks.  The amp is solid state, with two tubes in the pre circuit.  It may have a protection circuit.  I'll take a look for anything loose.
