I finally decided to let this go as I realize that it's not my thing. I bought this in January and it operates flawlessly!! The reason for slightly higher cost is that it has 12 Winged "C" (SED) 6L6GS tubes that now are valued at $99 EACH! www.thetubestore.com - Winged "C" (SED) 6L6GC Audio Tubes I do not want to ship this but I will if you are willing to pay the cost. It is a huge PITA to prep. (I can number and ship the tubes and ship separately).
