In Reply to: Tube rolling preamp or power amp gain tubes, which ones (or both)? posted by 2121@comcast.net on January 16, 2017 at 04:46:39:
I have 2 sets of every tube used in my system except the power tubes. I've swapped the pre-amp tubes and the driver tubes in my power amp. I can't hear any difference. I can't swap the power tubes as only one brand will work. The Sovtek 6B4G is overspec'ed and a NOS 6B4G would not be able to take the power, at least not for very long.
My pre-amp used 6GM8, and I have a quad of Bugle Boys, and a quad of something else, and my driver tubes are a quad of orange globe 6DJ8, with the second set Sylvania 6922. People hate the 6922, but I can't tell.
