Krell fpb 250m


Hi, got a krell fpb 250m, when you turn it on, itll do it thing then the breaker in the back will trip... no smoke no smell... is this a major issue? I wonder if i have to send it to krell or just a local repair guy

So i have the schematics and my tech told me that one of the power transistors is burnt, 484002.. called krell and ordered one.. its now being fixed and hopefully that fixes the issue! 
Drive both to krell for service.  Get a room for a week or 2 to wait for service!

   will never ship amps, etc again.  
  Take the time.  Those amps are wicked!

Can someone send me a copy of the schematics, one amp gets very hot and shuts itself down, led goes out at power up another issue. my tech needs the schematic to bias the faulty amp
