It seems that Wuben has great and well structured drivers! 
This is Tom E’s photo of the T70 driver:
Posted here: “REVIEW” - WUBEN T70 Camouflage – XHP70.2 Led – 4200 Lumens [PIC HEAVY] ***Extension tube = 2 x 26650*** - #14 by Tom_E
BTW, gchart, when I got my first TO50R sample for review, I had some “electronic” problem that after turning it on in Turbo 2 or 3 times, it stopped working on the Turbo level, I could only cycle between some modes (ML-L-M-L-ML - yeah, it was acting weird too!).
I sent it to Wuben again, to China, and they sent me another one! Jelina later referred that there was an hardware problem.
I do hope you can manage to make it work again, fully, and with those extra leds 
It looks great!
