Does R refer to the year it was built and the following number is which one it was from that year, in this case the 30,110th? Does VR mean 2006? The serial numbers just run in sequence and don't refer to any year. The "R" just means Rectifier or Recto I'm guessing. Your friend's amp was the 30,110th Recto ever made. My Dual Rectifier is R-00246. It just signifies that it was the 246th Recto made. Mesa used to date the inside of the chassis. That is how some people know when their Rectos were made. Other than that, you have to call Mesa with the serial number. Dale
