Mk171 voice changer power issue

I have soldered the kit and have encountered a problem with the power. The (brand new) battery is connected and so is everything else. I tried the switch both ways and there was no power to anything on the board, not even a flicker or crackle. I have tried all the tips I could find on this website, none have worked. So what now?

Could you post a picture of the PCB? Top and bottom
