Hey, I’m curious if you still have that amp and if you’re running KT88’s with it or the 6550s still as I have the same amp and love it ⭐️ Also, when I did have the MB450’s the first generation I used KT120’s with it and loved it. It’s too bad VTL Doesn’t make any new or amps with the bigger tubes like Conrad Johnson does imho they are missing the boat
