@@kofikwakyeagyekum6487 can you try to test out a different audio source ( input) it could be your input gain is too high . Or possibly the speaker is overloading.
@@sharndhayanithi1856 that is not the case sir, I have tried Tuner,phone,tape1 tape2,cd and different speakers sir but all sounded same,if I play Only the preamp direct , still I don't hear that distortion, distortion is within the power amp
@@kofikwakyeagyekum6487 can you check if you have any defective capacitors in your preamp. Also connect a headphone to the amplifier output ( it's should be in the front ) and test if you have the same problem.
