I've visited 2 stores in the Atlanta area that carry tube gear, turntables and carts, etc. One guy swapped out carts and tubes while sitting on the floor during an audition. The folks at both shops were passionate about 2 ch. I hope they're still in business.

But, I go to Atlanta maybe once or twice a year at most. The 2 mid-sized cities closest to me have a small selection and the shops are mostly into home theater sales and installation. OTHO, my two favorites have been in business for a long time. The owners are still into 2 ch personally and have ways of getting equipment in for audition. It's cool because it's almost like 2 ch has gone underground. They bring you to the back office or leave the gear disconnected until their "special" 2 ch customers come in. However, if you buy, you get full factory warranty, service, etc. It's kinda like a legal drug deal. But even these guys draw the line at tubes and turntables so internet shopping was mandatory for my sources and amp.
