Nad M3 non repairable

I have a NAD M2  that after some many years sparkled and crackled  and died.   I suspect the cats warming themselves atop the unit  or old age rendered the unit dead.

Will NAD send me a box for an M2?  Can I ship the unit to NAD for repair? 

I did this once early i it's life (under warranty)  they shipped it back and it worked flawlessly for 7 yrs or so.

I REALLY love, well loved, the unit  and don't mind putting some dollars towards diagnostics and prospective repair  

I live in North Central Florida,   in a little city,  Dunnellon

any guidance or suggestions would be appreciated

Use it as a paper weight.
