Any one know of a tube amplifier repair technician anywhere around Raleigh, NC?

My 60wpc Muzishare R9 805 SET Tube amplifier integrated has been a heavy paperweight for well over a year.   I would like to get the bias circuit and input stage circuit working again.  I didn't know using it to handle only 250hz-20Khz for my Legacy Audio Whisper XDS speakers would be any issue. It's 3-way active crossover system, but two channels of the Wavelet II crossover are for the 15" bass drivers with one needing a time delay between the front and rear open-baffles for time alignment.  The speakers' quad-mid-woofers and dual-AMT mid-tweeter drivers are passively crossed internally,  I got pretty discouraged not finding tech before.  It's 90lbs so I am trying to avoid the shipping.  Thanks for the help!
