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

Variflex / PRODEX (Yoko / Dantax) Dansk HI-FI Microline type MX-60, 197?, made in Denmark
Cлучилось - производитель PRODEX ! На перепутье с Yoko, дизайн которых один в один как и Dantax (вполне себе производитель хороший, проверено лично). И все датчане постарались: Jens Thorborg. Доказательства
Когда-нибудь увидим, что там из чего сделано, звук феномен на ближнем поле, стоят рядом с Genelec 1029A & Genelec 1031 и работают в щадящем режиме, НЧ длиноход даже при таких размерах. Кто не верует - тот воли не знает.

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