BAT VK-P5 6922 tube question ?

I am trying to find out which 6922 tubes are the most sensitive for tube rolling. There are 8x6922 and 2 rectifier tubes. 4 pcs of 6922 are located the rear and the others in the center.
Thank you.

They'll have the instructions they can send you. I used to have them, but long lost. I think you'll love the better tubes. It's a great phono stage! It's not to hard and does make a difference when the bias is right...you will need a meter and a small plastic screwdriver, voltages are high inside there.
