the plastic replacement stand mount for the board seems to short for me. it's compressing the caps infront/under it. i was able to get the led to light up and correct voltage readings, and good sound but then a blown fuse, i replaced it with my crack fuse and then blown again. there was a humming noise and smoke the second time. i unscrewed the board now to allow space, replace the fuse again (but not sure if its a fast blow) and all sounds good. i think board compressing the caps was the problem so now its dangling below and working. but it doesn't seem like a long term fix. am i doing something wrong?
