RFT SDK 3930 Doppelkassettendeck aus der DDR ca. 40 Jahre alt. Einige LEDs leuchten und es ist ein surren hörbar, daher vermute ich, dass die Motoren noch laufen ansonsten fehlen mir die Möglichkeiten genauen Funktionstest zu machen. Da sich Kassettenfächer nicht öffnen und Vorlauf nicht funktioniert sind die Riemen mit Sicherheit zu wechseln und weitere Mängel nicht auszuschließen. Das Gerät ist also etwas für ambitioniertte Bastler und Liebhaber der RFT Geräte. Verkauft wird ohne Sachmängelhaftung bitte an Selbstabholer.
This is a clear buyer’s market for vintage East German cassette decks, and the €66 asking price for parts is a genuine bargain, sitting well below the typical used range of €150–€250 for working RFT SK 3930 units. Even for a non-functional deck, this price is roughly 25% of what similar models fetch in restored condition, making it an excellent entry point for a hobbyist or restorer.
The RFT SK 3930 is well-regarded for its sturdy DDR engineering, smooth 1-motor drive, and Dolby-compatible RMS system with dual LED level displays. It handles both Fe and Cr tapes with a frequency response up to 14kHz and offers solid signal-to-noise performance (>56 dB). For a parts-only unit at this price, the upside includes potential for full restoration, rarity in working condition today, and the chance to own a classic piece of Cold War hi-fi history with genuine character.

RFT, or Rundfunk- und Fernmelde-Technik, emerged in the German Democratic Republic (East Germany) during the Cold War era, functioning not as a single manufacturer but as a state consortium uniting numerous VEB (state-owned) enterprises in radio, television, and telecommunications. Active from the 1950s through the 1980s, it coordinated production across factories like VEB Funkwerk Köpenick and VEB Nachrichtenelektronik, branding a diverse array of electronics under the RFT label for domestic and export markets. This collective structure reflected the centralized economy of the GDR, with no individual founder but a legacy tied to postwar industrial revival.
The brand's product focus centered on consumer and professional audio gear, including bookshelf speakers, full-range drivers, vacuum tubes, and communications electronics like radios and two-way systems. Iconic examples encompass 1970s RFT bookshelf speakers with Tesla-sourced drivers, 1950s EGB (RFT) units for high-sensitivity radio applications, and ECC83 preamp tubes widely used in European amps. Amplifiers and turntables appeared sporadically via consortium members, but RFT excelled in affordable, robust loudspeakers and components rather than high-fidelity esoterica.
Today, RFT occupies a niche vintage-collector space among hi-fi enthusiasts, prized for its utilitarian GDR engineering and surprising sonic performance—often high-sensitivity designs that punch above their budget origins. Far from high-end or contemporary mid-tier contenders, these pieces appeal to retro hunters seeking Cold War-era bargains with character, though sourcing verified originals demands caution amid rebrands and fakes. Obscure outside specialist circles, RFT evokes affordable analog nostalgia without pretension.
