Telefunken RT 300 FM/AM Tuner, 1981, made in Western Germany

Service Manual: elektrotanya

Device Type
Digital Synthesizer Tuner

Start of Sale
1981

General Description
The RT 300 is the largest and most luxurious tuner of Telefunken's 1981 lineup. It offers almost all features one would have expected for a good tuner at that, with the notable exception of the timer functionality found in the RT 200, and the analog tuning wheel found in the TT 750. It can however still be regarded as a direct successor of the TT 750, since the digital tuning system is almost the same, built around three chips custom-made for Telefunken.

The RT 300 was part of Telefunken's T 300 high-end component system, and it has a remote control input that allows the drive functions to be controlled via the RP 300 pre-amplifier.


Features
FM/MW/LW, 40 program memory places, manual/automatic tuning, digital frequency input, LED field strength indicator, exact tuning indicator, fluorescent display, automatic muting via RP 300

Connectors
FM antenna (both dipole and coaxial), AM antenna, AF out(DIN and Cinch), Remote Control

Defil Lap Steel Guitar, 1970s, made in RPL - Polska Rzeczpospolita Ludowa

Universum System Hifi 7500 SL (V 2315A), 1981, made in Germany

Dieser Verstarker (V 2315) ist Bestandteil des Universum Systems Hifi 7500 SL. Zusatzlich angeboten wurden im abgestimmten Design ein Тюнер, ein Plattenspieler sowie Tape Decks in unterschielichen Varianten.
Der Verstarker wurde damals in zwei unterschiedlichen Varianten hergestellt. Die erste Version verfugte uber eine Raumklang-Einrichtung, mit Hilfe derer ein sogenannter "4D-Quadro Raumklang" erzeugt werden konnte. Neben der ublichen Stereo-Акустическая система wurden hierfur zwei ruckwartige Effektlautsprecher benotigt.
Eine spatere Version dieses Verstarkers hatte diese Raumklangfunktion nicht mehr, statt dessen wurde eine "Mute-Funktion" in das Gerat implementiert.
Besondere Kennzeichen dieses Gerates waren seine flussigkeitsgekuhlte Endstufe(Heat-Pipe), eine massive Front aus Aluminium, sowie ein vergleichsweise flaches Gehausedesign. Vermutlich steht in diesem Zusammenhang der Namenszusatz "SL", der in der damaligen Werbung zu dieser Serie als "Slim-Line" bezeichnet wurde.

Linn LK100 Power Amp, 1996, made in Scotland

The Linn LK100 Power Amplifier is a flexible power amplifier with performance and power to drive virtually any loudspeaker. It can be used with the Linn Kairn in a main system and is ideal for use in distributed sound systems.

Multiple outputs allow easy bi- and tri- wiring, and the affordability of the LK100 makes bi- and tri- amplification of loudspeakers more accessible.

The LK100 has over current and over temperature protection, an efficient internal heatsink, and is stable into any load. Additionally surface-mounted transistors on the circuit board provide efficient heat dissipation.

With output power of 50 watts per channel into 8 ohms, or 90 watts per channel into 4 ohms, the LK100 has the ability to drive the most demanding loudspeakers. Its elegant looks make it ideal for stacking in multi-amplifier and active systems.

Good looks combined with affordability make the LK100 a highly desirable amplifier, and its high performance gives it a wide range of applications, including driving Linn Kabers, or the active Keltik loudspeaker system.
