More tone, less dynamics
I put 3 of these in my Friedman Pink Taco. Positives: The tone controls came alive with these tubes, especially the mid control. More bass, not muddy at all. Highs are good, not skanky. Negatives: The amazing dynamics of this amp suffered with the Tung-Sols. Im a medium gain player usually with gain at about 5-6 on this amp. I want some cleanup with soft picking too. These tubes don't have the gain of the stock ARS (Chinese) tubes - I was up to about 7 to get in the ballpark of the stock tubes. At that setting soft picking is still pretty gainy and my R9's volume knob cleanup just wasn't good at all. I put one of the stock ARS tubes back into V1 and the dynamics returned. With the Tung-Sols in 2 and 3 the amp retained some of the extra tonal control and bottom end, so for me, there was some improvement with the mixed set. I just didn't dig it in V1.
