Sony integrated amp trouble shooting no speaker sound

[spunky35070]

I have a sony ta-ax44 integrated amp I just bought and was testing with gradual increases in volume with 500 watt speakers ( amp is 100 watt ) the power remained on but speakers not working it was only about 50% volume I turned down volume and even turned off hoping for reset. I looked for fuseable link inside what should I do thanks

plug in a set of headphones.
if the headphones work, you blew the speakers. if the headphones don't work, you blew the amp.
