TRANSFORMERS
The main component of a 70V system is the speaker transformer. Its secondary winding has taps at various
impedances. You choose the tap that matches the speaker impedance. For example, if you're using a 4-ohm
speaker, connect it between the 4-ohm tap and common.
The primary winding has taps at several power levels. These power taps indicate how much maximum
power the speaker receives. For example, suppose you have a 70V transformer with the primary tapped at
10W and the secondary tapped at 8 ohms. Then a loudspeaker rated at 8 ohms should receive 10W at its
voice coil when the primary is connected to a 70V line.

The purpose of this Transformer is to match the Impedance of the loudspeaker or a number of loudspeakers to the optimum load of the tube or transistor. In other words, the transformer transforms the Impedance of the speaker, so that the impedance which it presents to the primary winding is equal to the load of the Output stage active element (tube to transistor).

An isolation transformer is a transformer used to transfer electrical power from a source of alternating current (AC) power to some equipment or device while isolating the powered device from the power source, usually for safety. Isolation transformers provide galvanic isolation and are used to protect against electric shock, to suppress electrical noise in sensitive devices, or to transfer power between two circuits which must not be connected together.

Suitably designed isolation transformers block interference caused by ground loops. Isolation transformers with electrostatic shields are used for power supplies for sensitive equipment such as computers or laboratory instruments.

A Control Transformer is a transformer which supplies power to control and /or auxillary equipment not intended for direct connection to the main circuit. Control transformers are specifically used to provide control supply voltages for the control circuits of AC motor starters.

Auto Transformers are actually built with the equivalent of only one winding.  Two-winding transformers can be connected to reproduce the same effect.  The single winding version has as a limit that it is most efficient when the difference between the input and output voltages are closest.  As the difference becomes greater, efficiency suffers, and so does the advantage of this design.
