Yup, its one of the early models that he was selling to board members back in 2004, Its in perfect condition, there is not one blemish on it what so ever. I used this with a couple Dynaco Mark III's that Craig (NOSValves) had completely rebuilt for me, triode boards, seperate bias for each tube, banana connectors, etc.... Man what a sweet setup that was with my RF-7's, mind you this was back in 2004 and 2005.
I literally used this preamp for maybe 3 months and then i boxed it up due to moving and going into the Army, for years it sat boxed up in my closet back at home in Texas, then finally after 7 years i pulled it out over a year ago and sent it in to Mark to have him look it over and he checked it out, serviced it and sent it back to me and i never took it out of the box till just a few days ago, it is mint!
