Sony TA-N86B Power Amplifier – Silver

In really lovely late 1970s stereo amplifier from Sony. Switchable between Class A, B and as a Monoblock. In generally very good cosmetic condition, full working order, with a few small nicks / marks. It has its original box and comes with 3 months warranty.

Description

The TA-N86 power amplifier is a powerful and technically advanced audio amplifier offering superior performance.

Each stage of the TA-N86 employs a DC amplifier, and by using matched pairs of transistors, a considerably better temperature characteristic and stable operating point under all signal conditions is obtained.

The differential amplifier uses no coupling capacitors and is well suited for the amplification of low frequencies.

Pulse techniques are utilized in the power supply section, which by reducing the weight of the power supply components, contribute to an overall weight reduction, as well as furnishing a highly regulated power source under all conditions of signal input or line voltage fluctuation.

The TA-N86 employs a newly-developed Hi-fT transistor with excellent linearity at high frequencies and high current levels. This transistor greatly reduces switching distortion at high frequencies.

In addition, the TA-N86 includes a three-stage differential amplifier in the voltage-amplifier section, and a three-stage Darlington configuration in the power-amplifier section all of which aid in providing superior distortion characteristics.

Each circuit of the right and left channels in individually laid out. This contributes to the excellent channel separation.

The TA-N86 can be operated as a class A amplifier, a class B amplifier, or a mono amplifier by means of the Operation Switch.
