You are fortunate that the input tube is the tube that matters most according to J..128 for the Rougue. There are so many option available, I have tried a bunch of 12AX7 tubes each has its own characteristics. I would try as many as you can afford to find the one you like best. I use Telefunkens and Mullards most of the time. The telefunken is very clean sounding while the Mullard is "Polite". The drivers are reportedly very important again there is a plethora of 12AU7s to try and they are relatively inexpensive. I have found it to be fun trying different tubes and I like the variety of sound I can achieve using different tubes. The only problem is that it can become addictive.
Tube rolling suggestions
I purchased a Rogue M150 several months ago (my first tube gear). I would like to try some tube rolling and have a few questions I could use some help with. Which tubes have the greatest affect on the sound of the amp Input, Driver or Output? Any suggestions regarding replacement tubes and their characteristics will be appreciated? The stock tubes in each mono block are all Electro Harmonix, drivers are (2) 12AU7, input is (1) 12 AX7, Output are (4) KT88.
Thanks in Advance
