Kettle,
Below from Cary's Billy Wright
"The front and back 6SN7 tubes are the input tubes. The ones left and right are the driver tubes. It is more important to make sure the input tubes are matched, and they also benefit more if you want to upgrade tubes such as NOS. I would still recommend matching the driver tubes as well."
Good Listening
Peter
