What is stereo?

There are now two system of high fidelity, monophonic (monaural) and stereophonic. Monophonic is a system that starts from one microphone and is fed through a single high fidelity set. Stereophonic is a double system. Two separate microphones are placed at different sides of the orchestra and two different systems are used to keep the two signals or channels separated. Two separate speakers are used, placed on different sides of you room. Stereo is much like 3-D photography, two slightly different sound reach your ears giving you a new dimension in sound.

Sony TA 88 (1970)

Integrated amplifier in woood-finish cabinet.

His form is perfect for not clutter, and weighs only 3.2 kg: it is really practical!

Simple circuitry, construction exemplary and very reliable
