With radiator, of course.Unch is blind to the 'china' standard. We need to refine.Necessarily inlet ceramic-ii-replace with film! The sound is much better.In addition, on the input of the amplifier before this-ii-put the divider in the form of rc chain. Find information on the network. As a result, fewer leads and noise.Increase the capacity of large electrolytes to eliminate distortion at high volume.In general, it is desirable to replace all electrolytic-ii-with high-quality audiophile.Quite for advanced-at the output unch before the speaker to make a throttle.Do not give more than 20-24 volts in each shoulder.Do not forget about the quality radiator!The rest at will...
