1. You posted it in the wrong section
2. You are new, not great first posts, at least have some respect for forum members and get to know them before trying to sell your stuff to them.
3. You are way over priced on your price, do some research, DC5 combos sell for about $500 on ebay all day long. The heads go for a little more.
4. If i only had a dollar for everytime I heard new tubes, mesa of course, which usually means they are the original tubes and someone is trying to claim they are new. Hope you can produce a receipt, if not i would expect anyone to believe they are new!
