TELEFUNKEN Concertino 6

When you listen in on this device, “energy” is the first, instant impression you can get.
A "swaggering" radio, with muscles and no awe.

I would not have thought it possible to have such a result with one single EL84 and one woofer, this Concertino 6 gives off a truly remarkable sonic impression instead.
I found it especially suitable for Jazz and lounge music. Sax, double bass, drums are best to be listened to.

Due to the smart arrangement of the speakers this model can be placed on bookcases as well as on pieces of furniture that are open on all sides.

Indeed, the cone tweeters are arranged on its corners, thus ensuring a linear playback both frontally and laterally.
Certainly, the placement of the speakers has led to the construction of elaborate wood stands inside the cabinet; although complexity has never stopped German engineers.

The radio section is clearly up to the brand. Tune stability and lack of noises are usual features of the devices I choose to restore.

An extremely solid and “reassuring” device. Certainly among the best in its category.

AERIALS

Inside the cabinet there is a dipole for FM reception and a ferrite rotating aerial for AM reception.
The ferrite antenna rotates by means of a large knob situated behind the volume knob.

The reception sensitivity with internal aerials is very good.

Using an external aerial sensitivity is further increased.

This unit was in fact produced in a period when there were not many radio stations and those available fairly apart from each others.

TONE CONTROL WITH LEVEL INDICATION

The tone control system is very efficient. Above the large tone control knobs there is a band that lights up gradually indicating the emphasis on the band on which it acts.

SEPARATE CONTROL PROGRAM BETWEEN AM AND FM

The tuning system is another gem.
The unit is equipped with mechanisms for keeping separate the AM bands by the FM bands.
The tuning knob is single but a selector switch commutes into cable systems (all in steel) and pulleys separated depending on the band.

CONTROL PANEL

The volume control is on the left (with built-in loudness) and axially, the command of the ferrite antenna rotation.
You can see the indicator of the position of the antenna, the magic eye that indicates the perfect tuning of each station, the scale for Long Medium and Short AM waves, and the FM scale.
Below, from left, there are, in order of appearance, the bass control knob, power buttons, record player, tape recorder, keys for tuning Long Medium and Short Waves, FM, and the knob for the treble control.
In the middle between Long and Medium waves we find the knob for the narrow tuning.
Finally, the movement of the tuning knob is very pleasant being supported by a two large flywheels.

A big elliptical broadband speaker is placed in front.

The two tweeters are placed on the corners to create a 3D effect.
