Caution!

Change the loudspeaker leads from one loudspeaker to the other. If the fault remains in loudspeaker ‘A’, then loudspeaker ‘A’ is at fault, go no further.

If the fault now appears in loudspeaker ‘B’ then the problem lies further up the line. Move on to step 2.

Change the loudspeaker leads completely from left channel to right and from right channel to left by now swapping them at the amplifier output. If the fault now appears in loudspeaker ‘B’, then that loudspeaker lead is at fault, go no further.

If the fault appears in loudspeaker ‘A’ then loudspeaker leads are OK. Move on to step 3.

Restore the loudspeaker leads to their original connections at both ends.

Change the input plugs on the rear of your amplifier, as follows: Change each input source in turn by swapping the plugs left to right and right to left.
