Agreed. 12BH7A (CV5042) can be great. Curious if the Trumpet could facilitate it.
Doesn't this rely on the power supply? As I am running the SBooster LPS, it is capable of 2.5A @15v, the stock Hagerman w/wall wart was designed for 2.05A @15v. So, as designed, the SBooster (in theory) has more current available than the Trumpet was designed for, which is good. But, may not be enough for 12HBH7A's if they call for 3A.
I might have this all wrong, just learning here. From what I am reading, it is the power supply that could be damaged by not being able to provide enough current, (in my case), not the Trumpet itself.
