My Experience Favors the Stock Sovtek Tube

Posted by Mister Pig on August 3, 2002 at 09:34:49:
I have a current version AIM 3A, and the tubes that I have run through it are as follows, telefunken, siemmens gold pin, amperex, and edicron. The edicrons were my favorite of the non sovtek tubes. In the end I found that all the other tubes skewed the tonal balance in my system in a manner that was to difficult to live with over time. All of them pushed my system to a point that was too warm. My first concern in a system is to get the tonal balance right. And I belive that AI does that reasonably well in its overall design. And I haven't found the need to replace the sovtek tube. Although I am intruiged by the russian military tube. Another problem I found with the AI when rolling tubes is that the NOS tubes always affected inner detail and transient response negatively. If you roll tubes in the AI, be sure to have some good Sovteks around that you can compare against.
