Are you sure it's not the channel itself?

Hi

My english isnt the best :-)

Channel? do you mean radio channel?
The noise "scrats/hiss" is there both when using radio and tape. And when gently pushed in top of the bass unit.

Dont know if "weak hiss" is the right word, but when i gently push the bass in the top i can hear and fell that there is opposition(resistance), there are not any opposition/noise in buttom of bass, when i put a finger on the bass (when playing music)in the buttom(6 oclock) the scrats noise disappear a little.

There aren't any noise/resistance on speaker 2 it sounds perfect for its aged :-)

OK. Take the good speaker and plug it in where the bad one is. Then listen. Tell me what happens.

The result is the same speaeker A still sound strange.

But it is only VERY bad when playing electronic 80/ebm music, just have an hour with pop /hit music on the radio it where "okay", but when i played some electro 80/90 music, jesus the speaker B sounded like s...

OK, sound like you have a problem with the speaker AND the output channel. A is left and B is right.

Take your good speaker and try it on both sides. (plug in to left first, then right)Which sounds worse?

Then take your good speaker, do the same. Is it bad on on side only? Does the bad speaker sound better on the left (A) or right (B)?

Use the electro music as it tends to be bass driven. Turn the treble and bass all the way up and add volume slowly. Do not turn it all the way up, just about 1/3 and see what happens.

okay i called defect speaker A (right)now we call it B right

It is still the same, speaker B does sound wierd when put in a or b on he box.

and this is ??

There aren't any noise/resistance on speaker A(LEFT) it sounds perfect for its aged :-)

Then a bad speaker is likley. Hunting replacement spekers hopefully wont be tough.
