B&O Bang & Olufsen Beomaster 900 M all transistor stereo type 2205-5 serial #30079, 1964-1970, made in Denmark

The inspiration for the Beomaster 900 came from the brains of Henning Moldenhawer.

The first product of the new era was launched in 1964.

Beomaster 900 was a fully transistorised radio with FM stereo radio. It was even launched in a version with two built-in speakers - Beomaster 900K - making it clear to everyone that it contained two independent stereo loudspeakers. Bang & Olufsen wanted to design a product so unique that it would open the doors to distribution throughout Europe, in the same way as the “Five Lamper” had done in Denmark 30 years earlier. beoworld

Palladium NSA-7000 Stereo Amplifier (955/531-1), 1985, made in Germany | MCS (Modular Component Systems) 3847 | NEC AUA-7000E

Разработан в эпоху «золотого расцвета» с минимальным использованием интегральных схем. В системе питания используются конденсаторы с емкостью 2x10000uF что устраняет так называемый эффект «шума сети». В предусилителе используется конденсаторы Rubycon, потенциометры ALPS. Для построения выходного каскада мощности использованы 2 пары транзисторов Nec.

Построен на базе тразисторов NEC:

2 x D588 R7YD

2 x B618 R77B

Sakevich SK1200 Studio 2

Link: ixbt | muzbazar

контрольный усилитель мощности, настоящий класс А, который сейчас не встретить за такие деньги. Звук на уровне усилитель Bryston, Filigrane, Pаrasound и т.п.

Предназначен для использования для применения в областях, где требуется высокое качество звукопередачи в сочетании с высокой мощностью - студии звукозаписи, кинозалы, и т.д. Имеется возможность подключения 2-х пар мониторов с возможностью их оперативного переключения. Важная особенность усилителя - регулирование величины выходного сопротивления, что позволяют добиться более оптимальной и качественной работы АС по сравнению с традиционным режимом постоянного низкого выходного сопротивления усилителя. Переключение выходной мощности позволяет безопасно работать с мониторами небольшой мощности.

RITM-2 | РИТМ-2 Analog One-Voice Soviet Synthesizer [Black Face], 1987, made in USSR

Link: ruskeys

Description

This synthesizer was manufactured by Kirovsky musical instruments' factory in 1984, designer - Viktor Nikulin. The EMI Ritm 2 is an one-voice keyboard synthesizer designed for solo, ensembles and orchestral playing musical compositions of any genre. It can be used both for educational needs and creating different musical effects. This synthesizer can be used with an acoustic amplifier which has a response of 0,775. There is a possibility to use a low frequency amplifier such as radio receiver, TV and tape recorder. The quality of the sounding depends on an acoustic amplifier.

The synthesizer Ritm-2 can play soundings of the other classical instruments (keyboard, strings, reed and percussion instruments). It is intended for creating some specific sounds (wind, noise of surf, train, gun and whine). Using this instrument one can play some compositins with a random pitch and a timbre.

Körting (Neckermann) Hifi Studio Multisound Art. Nr. 955/728, 1973-75, made in Germany

Четкий, точечный, размеренный бас! Cередина и Верх детальные и рассыпные.

Очень очень приятно слушать Блюз и спокойный Джаз.

Достойный звук для видавшего виды...! С Isophon и Dynaco проявил себя с объемом взрослого звука.

Рекомендую взрослому слушателю, именно тем, кто уже научился слушать музыку за многолетнюю практику!!!

В одном из фейдеров сохранилась шторка, которая защищает фейдер от пыли, великолепное исполнение для 73-го года!!!
