Question about Audio Players & Recorders
Without hearing the distortion, it will be difficult to state with any confidence where in the amp the problem exists. That being said, the most common problem is with the preamp section. Many of these use 4558 chips as the pre-amp section. If hte chip is blown, the sound may still be heard, but it will be distorted. This is easily seen on a scope. The chips can be purchsed in bulk for les than $1, so the parts cost for the repair should be low.
