I use Al Forbes at http://www.alphasoundandlight.com/ he is a great guy. He does soo much guitar amp repair / tuning it's crazy. He actually does Willie's amps.
Amp Repairs in Eastern North Carolina
Moving shortly to eastern North Carolina (Fayetteville) and looking for a source that can do quality work on tube amps (Jolida). I'm guessing the Raleigh/Durham area might be the closest cities where I could find someone who could do such work. Anyway, appreciate all suggestions.
