Ordered a BMAX-T, should be here next week. So many questions. Will 48V phantom power fry the DI output? Hate to find out the hard way. If necessary it can go through a passive DI box on the way to the board. Next, has anyone experimented with different tubes? I've got some NOS Tungsram ECC82 and ECC83 tubes that I would like to use in something before I die. A bunch of these tubes have been sitting in a padded box in the bottom of my gig bag as long as I can remember. Since I may be opening up the BMAX for the Blue Light conversion project, what about a tube swap? From what I read, there is plenty of gain as is. What would happen if I stuck in a lower gain tube like an ECC82 (12AU7)? With all the knob twisters and tinkerers on this forum I'll bet someone has tried this.
