Pioneer SM-83

Японский (мультивольтажный, в т.ч. и на ~220V) ламповый PP (Push-Pull) усилитель Pioneer SM-83, конца 60-х г.в. прошлого века, мощностью 2х25 Вт. и встроенным фонокорректором.

 Цена:  1100€ (Продано)

This is the original design of the Pioneer-and probably from 1967. According to the measurements of the power amplifier is around 25 watts per channel and is built on tubes manufactured by Hitachi. The steps under the lights worked 7189 according to the push-pull (PP), 6AN8 controlled lamps. The preamps and tone control systems work 12AX7 (ie, produced by the Japanese equivalent of ECC83). Amplifier 145W gets from the network.
     All used in the amplifier's capacitors are ELNA, and the rest are oil companies SUZUKI capacitors. Resistors are also SUZUKI (now that the company probably few people would associate with the production of resistors:))

     The amplifier has a major switches:

    * Changes in phase one of the speaker outputs (no need to especially pay attention to the connection of the speakers because we can always switch to "chamfering")
    * Change the location of left and right channels (no need to specifically consider the signal cables connecting because we can always switch places with the left-right channels).
    * Changes in the output resistance of 8 or 16 ohms.
