TELEFUNKEN OPUS 55 TS
Designed and created in 1954, the OPUS 55 TS was the flagship model of the entire Telefunken production for the years 1954-55.
Since 1949, Telefunken decided to distinguish by the name “OPUS” the radio models at the top of their production. In fact, the first Opus model is the 1949 OPUS 49. This denomination remains until 1978, when the last Opus model, the 7050 HI-FI, is produced. In the following years the different models will be distinguished by alphanumeric abbreviations, such as TR550 and such.
The restoration of this device was very challenging, as the chassis had been cannibalized. As a matter of fact, potentiometers, tube sockets, many components, wires were missing and the HF coils had been torn. In short, the device was in terrible conditions. But a machine like this deserved a much more glorious end and the final result proved us right.
The amplifier stage has been literally rebuilt, the very fine wires of the high frequency coils have been reconnected through a very meticulous work.
The phases of this challenging restoration are documented with photographs, which can be seen at the end of the page in the dedicated section.
The declared output power was 15W but judging by the scheme and the voltages it must deliver about 10.
The good amount of power delivered and the high efficiency of the 6 loudspeakers allow the Opus 55 to successfully sonorize large rooms.
The double medium frequency stage, the complex feedback network, the push-pull output stage make it a classy and elegant radio. The configuration of this device will remain pretty much unchanged also in the following models, until the transition to the production of stereophonic models.
The devices of the Opus series are still among the most wanted by collectors for their extremely high quality standard.
The songs in the playlist highlight the incredible virtuosity of the performers. All these tracks were chosen specifically to put the device to the test. Below is a brief description.
- The first song proposed is a flamenco. Inspired by Playa la Barrosa in Cadiz, Spain, it was composed and interpreted by Paco de Lucia. The talent of the Spanish Maestro makes flamenco enjoyable even for those approaching this peculiar musical genre for the first time.
- With the second track we fly to Paris to meet the Russian-Israeli trumpet player, Sergei Nakariakov. Known as “the Paganini of the trumpet”, Nakariakov's work is fascinating because it continuously experiments with transcriptions of songs composed for other instruments, such as the song proposed here, “Moto perpetuo”, written for violin by Paganini himself.
- The third song, known as “Vento d'inverno”, ranked as op.25 no.11 is a technical study written by F. Chopin in 1836. This study was specifically written with the purpose of developing technique and endurance. It deserves to be seen played live, as it is truly disconcerting. However, Chopin did not mean to impress his listeners with the demonstration of his skills, but he believed his fingers to be “handmaidens of his soul” and with his soul he wanted to be heard, not with ears (H. Heine).
- The fourth track is a 1987 song taken from the album “Surfing with the alien” by guitarist Joe Satriani. An album that was recorded on the cheap, with a very limited budget, the three guitars used by Satriani were modified by him and electronic instruments were used to simulate many drum effects. However, the album was extremely successful thanks to Satriani's skills and creativity. The proposed song is a remastered edition of 2014.
- The last track, “Drum solo”, is a live recording of a performance by Daniel John Erlandsson (Malmö, 1976). Erlandsson is a Swedish drummer, who became successful with the metal band Arch Enemy. It is characterized by a very precise ritmica suono that mixes classic metal passages with the death-metal typical of his band. The song is undoubtedly exciting even for the non-lovers of the Metal genre.
