Distortion on Power Amp that goes away when tapped?
My Nikko 230 gets distorted until I lightly tap the back, in that area of the cooling fins, and then it goes away. I took the top off and nothing seems loose. Any ideas?
Thanks |

Will need to gain access to the bottom of circuit board and look VERY closely with magnifying glass at solder joints, especially on output transistors/IC (don't know amp). You will be looking for fine circular crack in the solder - resolder it and it should work again.
