:sweat: the manual for the elise isn't exactly detailed, the tubes come packaged with a number assigned to the slot and you put the tubes in based on the number according to the manual. As I did not receive the amp with the original packaging I had to just take a guess. I figured out which tube...

Oh boy swapped both tubes and the popping and crackling swapped but it also got louder and much worse/frequent. At least it's not the amp(?) itself thankfully.

I have received the amp and it works(?), loving the sound of my HD600s on it and the focal clears are even more fun on it. However, there is an occasional popping/crackling in the right channel.
