Radio Grundig 3055 W/3D Klang, 1955

Around 1955, 1956 this was a top radio with its huge dimension and the contrast between the black of the mahogany finish, the ivory of the keys and the gold of the dial and of many other details. The radio has three AM and two FM bands with three tuning dials, for AM and for each FM band. Tuning dials are driven by a single knob, with a complex three way clutch system, so to have up to three preset channels. Built-in ferrite rod antenna can be oriented from the panel and the direction is indicated by a lighted dial. The radio has separate bass and treble tone control: the treble control also varies the coupling of two IF transformers and, then, the AM bandwidth. The output power is limited to about 4 watts, however the radio has five speakers: one large elliptical speaker, two electrostatic tweeters on the front and two dynamic tweeters on both sides. Seven tubes plus the selenium bridge rectifier: ECC85, ECH81, EF89, EBF80, EABC80, EL84, EM34/35, B250C100. Key features:    

Radio Graetz Melodia M 518 Raumklang Gross Super mit schallkompressor, 1956

This radio, built around 1956-1957, looks very modern, due to its sharp corners and to the light colours. Its huge cabinet, the plenty of keys and knobs, the massive brass grid over the speakers, all talk of a high-class radio. Great care is given to the audio section, with treble and bass tone controls or alternate tone register keys, 3-D sound key and the impressive speaker system: two large elliptical wide band and a small conical mig-range on the front panel, plus two fluted radiators on each side, feeded by a single horn tweeter driver. Four speakers all driven by a single EL84, 4 watt output audio stage! Other features are quite common in German radios of the period. Quite unusual is the magic eye saving key button, which switches off the magic eye when not needed for tuning. Tubes: ECC85, ECH81, EF89, EABC80, EL84, EM34, plus the selenium bridge B250C75.

This medium priced radio was in production around the late fifties. The radio widely uses printed circuit boards tied to the metallic chassis. Treble and bass tone controls and four key registers. In this model we see an attempt to brush up the old electrostatic tweeter, because its presence could be attractive for inexperienced people: an electrostatic unit was mounted beside the large elliptic speaker on the front panel. Tubes: ECC85, ECH81, EF89, EABC80, EL84, EM84, plus the selenium bridge rectifier.
