Recommendations for tube preamp (Emotive Audio Sira) repair in the Raleigh/Durham NC area?

My apologies if this is posted to the wrong section!

Does anyone have a recommendation for a shop or individual who may be able to help repair an all-tube preamp, in or around the RTP region of NC?

I have an older Emotive Audio Sira preamp, and (it seems) a couple of the tubes have stopped receiving power. My limited knowledge and googling seems to indicate that this might be a problem with a shorted filament or possibly a loose wire. 

I've reached out to Fred at Emotive but its been over a decade since I've spoken with him, and have no idea if he's even still active or would be a resource. While I wait to (hopefully) hear back from him, I'm looking into other, more local options. 

Any suggestions would be greatly appreciated!
