I just recently purchased a new ART levelar tube compressor for my rig, from Musicians Friend. Upon opening it up I found that the tube inside was a JAN Phillips 12AT7. On their website it states that it comes with a 12AX7. Also, I would doubt that they would ship these out with JAN Phillips tubes. I know some of you have these, I want to know what tube you got with yours. I also have sent ART and Musicians Friend an email regarding this. I have a strange feeling I got a used piece of equipment. It works, but if they want me to keep it, they better give it to me for a better price!
