Brief history of Romanian radio production
In the late '70s "Electronics" factories they started to produce radio receivers with accessories: Cronos (with electric clock), Interson, Express, Superson (with electronic light organ) and Ultrasound. Between 1960 and 1980, "Electronics" produced approx 75 types of devices in over 200 variants, totaling over 6,7 million devices produced.

What is Superson?
Superson is stationary radio receiver, manufactured in two variants between the years 1977 and 1979, provided with an organ of lights destined to receive the broadcasts of the broadcasting stations included in the range of medium waves (MA - amplitude modulation) and ultrashort (MF - frequency modulation). By attaching the light organ, a pleasant correlation is created between color and sound, giving musical auditions a special quality.
Radio Superson 1
Superson 1 (as the original part) works in the medium wave range 535 - 1605 kHz and in the range of ultrashort waves 65-73MHz. The value of the intermediate frequency signal is 455 kHz for medium waves (MA) and 10.7 MHz for UUS (MF). The receiver consumes from the network 220V about 6VA.
Organ of lights uses low power bulbs 6V / 40mA on each of the 3 channels: red - low frequencies; yellow - medium frequency; blue / green - high frequencies. It is practically the electronic kit "Miniorga de lumini" produced by IPRS Baneasa - Prospect 8202.
Radio Superson 2
The radio receiver is built in the same way Superson 2 having a more rounded shape than Superson 1, as can be seen in the image below:
Of course later, the transmission band of the radio stations changing, these radios with the frequency band OIRT 65-73MHz, were pulled in the band CCIR 88-108 MHz.
Electronic scheme
For a better understanding of the functionality of the Superson radio we will need the electronic diagram presented below:
Also, for a much clearer view of this radio, I have attached below some pictures from inside one Supersonic 1. Thank you Mr. Adrian Frigo for providing pictures. These helped to complete the article.

Superson's light organ had three light bulbs with small colored filters in front of it! LEDs are not discussed yet!
From Superson I have the light organ, and from Cronos I have the functional Japanese watch…
Cronos - a radio that I liked… and the clock mechanism and the receiver! Something special about what had appeared up to that point.
Until I got thyristors, 6V bulbs were basic. And commanded by some AC181 they went more fascinating than those operated on thyristors.
Another article of great quality, congratulations!
They destroyed us! All kinds of Chinese that only work when you buy them! After '90 the plan was to produce nothing! AND THEY SUCCEEDED!
I still have a small organ of lights from Superson!
What is interesting is that nowhere is it specified that Electronica Bucuresti produced these radios without a light organ. I think there were probably two options for import (with and without light organ).
At the beginning, the MA MF radio was manufactured with a clock with a falling plate mechanism. When Ceausescu tightened the screw with the imports because that watch was taken from the west, one of the engineers from Electronica had the brilliant idea to introduce that light organ in the place where the watch was located. And so this radio with the organ of lights was born.
Interesting, but wasn't that watch for Cronos bought in Japan? Or then the west was Japan 🙂
I think so. Only the US and Japan did it. Western European companies do not. That clock synchronized with the alternating current network, ie it took its tact from the 50 Hz which in reality were 48… 49 and was left behind for good minutes every day.
The West was any capitalist country, even if Japan is the most geographically eastern. When we also adhered to the European standard, ie 230V and 50 Hz nailed down, the electronic clocks with network synchronization started to work correctly.
