Sure, Audio by Van Alstine has been around since at least the late 1970's. Van Alstine has made a nice living doing complete re-builds of tube equipment originally made by other manufacturers, such as Dynaco. His products perform well, although they are not state-of-the-art, and they offer solid value. I have not listened to any AVA products in a number of years, but a good friend of mine had a preamp and power amp from AVA that sounded very nice.
