I've asked this question to qtan when he started to sell the Pure w/ PBT caps, but he didn't know the answer. I really like the PBT caps they are selling on the non-LED version of the Pure, and apparently they don't have plans to sell the caps separately, so that's the only way to get them. But I really want my Pure to be backlit, so what I'd like to know is if anyone can test their non-LED Pure to see if it still has the traces to power the LEDs or if they were removed from that PCB design?
