Hello!  It's my turn to ask for help!  

I have a Crown K2 that have an intermittent problem, it's like it won't stay powered.  You turn it ON, it will stay ON for 2-3 seconds, then shut down.  Going OFF-ON-OFF-ON several times and eventually it will latch ON and stays.  I then let it alone and it can be OK for weeks.

I have a service tech into this and troubleshooting suggestions would be apreciated.  Seems the relay that bypass the turn-on surge protection resistor is not getting activated.

That's a very early unit.  Actually, I brought the amp at the service place to have the power-saving function time-out modded so the time constant is longer, per Crown official procedure.  And the issue poped again while at the service shop.  I should have left the thing alone in my rack!  :/

Thanks!
