| | + | '''Besondere Ausstattungen''' |
| | + | * Trägheitslose Aussteuerungsanzeigeröhre (Magisches Band), ab 1967 Doppel-Drehspul-Zeigerinstrument |
| | + | * de Luxe: Abschaltbare Aussteuerungsautomatik (erstmals in der Tonbandgeschichte auch für Stereobetrieb) |
| | + | * Multiplay-Mischregler zur Aufnahmeaussteuerung |
| | + | * Ohne Stereoverstärker gibt das Tonbandgerät im Stereobetrieb den rechten Kanal wieder und kann mit einem Monoradio (Verstärker) den linken Kanal abspielen. So entsteht bereits eine breite Stereobasis. |

| − | '''Special Features'''
| + | == Berichte == |
| − | * Inertia-less level meter tube (magic tape), from autumn 1967 (radio exhibition) double moving coil meter.
| |
| − | * Switchable automatic level control (herewith 1966 for the first time in tape history also for stereo operation)
| |
| − | * Multiplay mix control for trick recording level control
| |
| − | * Without stereo amplifier the tape recorder plays the right channel in stereo operation and can play the left channel with a mono radio (amplifier). This already creates a wide stereo base.
| |
| − | * Depending on the headphone connection type (2 DIN jacks!) only one channel can be heard for trick processing; during playback also both channels, dual mono or stereo.
| |
| − | * Automatic STOP at the end of the tape
| |
| − | | |
| − | == Remarks == | |
| − | * Also as [[Grundig TK 247]], then fully transistorized with two built-in 4 watt power amplifiers, without automatic level control.
| |
| − | * The name suffix "de Luxe" was added to all mains tapes until 1968/69, some units before 1966 got "Luxus" or "L" as suffix. From 1969/70 on you see "HIFI" or "HIFI Stereo".
| |
| − | * "de Luxe" was written from the beginning, already in 1966, on the front cover (AUTOMATIC de Luxe), then from autumn 1967 additionally on the sound head cover (photos), under the mains selector switch (as on the [[Grundig TK 247]]), as well as in the updated user manual in many places, while other passages and photos correspond to the first version. Both stereo channels are still controlled together via ONE control, or via automatic.
| |
| − | | |
| − | * "de Luxe" is not in itself a sufficient indication of vintage, as erroneously claimed in some posts. If you are looking for the more modern double hand instrument, you have to rely on photos or descriptions of the vendor in this regard. Sales forums use the same name for both versions.
| |
| − | | |
| − | * Note: the mains selector was delivered on 220 volts. Since 1987 the mains supply is 230 volts and the selector switch should be changed to 240 volts with a coin (photo) - to protect the unit.
