Default 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.

Cheers
Graeme
