Telefunken TR-350 HiFi Stereo/FM-AM Analog Receiver, 1979-1981, made in Germany

General Description
If all you wanted was a simple Hifi receiver in 1979, Telefunken's TR 350 might have been a possible answer. One could call this device a crossing of the TT 350 tuner and the TA 350 amplifier. The tuner section is exactly the same as in the TT 350, even located at the same place in the identical housing, just without the variable FM muting level and exact tuning indicator the TT 350 features (it would be possible to add such an indicator by adding a few missing components on the tuner board). The amplifier section is the well-known Hifi Chassis 1000, also used in the TA 350. The housing doesn't look as empty as for the TT 350, yet there is still plenty of space.

Features

FM/MW/LW, tuning indicator, muting switch, selectable automatic fine tuning, monitor function, selectable loudness,

Connectors
AM antenna, FM antenna (coaxial and symmetric), Phono (DIN and Cinch), Tape (DIN and Cinch), monitor (DIN), ground clamp, 2xspeaker (DIN), headphone (DIN and 6.3mm)

B&O Bang & Olufsen Beovox HT S45 type 6302, 1976-1977, made in Denmark

Link: radiomuseum | beoworld | restoration | hifi-wiki

A compact 3-way loudspeaker of excellent quality designed for use with mid-range models such as the Beomaster 2000, 3400 and Beocenter 3500. The 3½ midrange driver was designated as a “phase link” unit, and was intended to reduce phase distortion. Its cone was made of doped paper and even after a long period remained “sticky” to the touch. As with the rest of the original Uniphase range, the back was made of moulded resin, and contained shaped cut-outs to aid wall mounting.
