[released] 17mm 8x7135 with Zener & dual-PWM + stubborn: A17PZL

Incorrect. I just double checked. My 10uF caps are physically smaller than my 1uF caps. I also went over here and looked at bdiddle’s caps (#46). Bdiddle’s C1 is also physically smaller than OTC.

Grantman321’s caps are not backwards.
