no power on fender princeton 112 plus

@fita1200 start by checking the fuse to make sure that you have continuity. If you do and you have power on there, check the test points on the board (TP) to see where you are showing power etc.

You said that "Have checked on/off switch, (good), capacitor, no power coming out." It will help if you tell us which capacitor you checked and how you determined it was okay. Also, why you were looking at a specific capacitor. Post some good images of what and where you are measuring with your question. That way we can see what you see. Use this guide Adding images to an existing question for that.
