/* Using Transformers */
The following lines were added (+) and removed (-):
The output connectors on the Amp serve only a single speaker, or speakrs in a series or parallel circuit of the same resistance.  When using 3 or more speakers it becomes necessary to utilize a special transformer.The output connectors on the Amp serve only a single speaker, or speakers in a series or parallel circuit of the same resistance.  More complex speaker arrangements may be achieved with the aid of transformers. Transformers are not meant to be used local to the amp, but are to be used local to the speakers.  One transformer is meant to be used per speaker, in a 1:1 ratio with the speakers.   It is wrong to think that one transformer near the amp can be used to solve multiple speaker of multiple resistance configurations, as there is obviously already a transformer in the amp itself with leads going to the connectors of the different resistance ratings on the back of the amplifier.
