There's some good threads on the 9xT6 - search for AK-47. There's also a SkyRay 9X. I believe my driver is the same as pictured in the old threads for the AK-47. Originally Richie086 said he'd get something like 5-6A tail measurement, but on the newer ones, you get 3A -- just like I do. Clearly, the current sense or current limting resistors were changed. So my plan initially, is to add a resistor to boost amps, but also copper wire up the springs. Actually my + spring looks herrendously under size, so I'll be replacing it, and adding copper wire to it as well.
Here in the OP is a nice pic of the driver: https://budgetlightforum.com/t/-/16227
