![]() Mini autoradio estraibile per la gamma FM (88 - 105 MHz) che utilizza due transistor al germanio BF424 e un circuito integrato µA3089PC, un diodo AA119, un diodo zener da 5.6 V e un diodo varicap BA102. La Frequenza Intermedia (ZF/IF) è a10,7 MHz. L'autoradio poteva essere utilizzato in automobile tramite un apposito adattatore collegato ai 12 V della batteria che incorporava anche l'amplificatore Audio, e che forniva al Tanga l'alimentazione e il segnale d'antenna tramite una contattiera a 4 pin. Il piccolo adattatore-amplificatore da auto utilizzava un circuito integrato TBA810AS, montato su dissipatore, che poteva erogare una potenza di ben 5 W a 13.8 V. L'amplificatore doveva essere collegato all'antenna dell'auto, al positivo (+ 12V) della batteria, al negativo (carrozzeria dell'auto) e a un altoparlante da 4 OHm e di almeno 10 Watt. La radio poteva essere ascoltata anche in casa utilizzando un altro adattatore (A544) che disponeva di un alimentatore da rete (220 Vac 50 Hz), di antenna a stilo e di un altoparlante incorporato. La piccola autoradio era fornita anche di una custodia in similpelle in cui riporla una volta estratta dal supporto in auto. Le dimensioni del Tanga erano davvero minime: 7 x 4 x 2,5 cm / 2.8 x 1.6 x 1 inch, e il peso di soli 69 g / 2.4 oz. La Voxson vendeva la minuscola autoradio estraibile in tre modelli che differivano per la gamma di ricezione e per il colore: Giallo per le Onde Lunghe, Rosso per le Onde Medie e Verde per la gamma FM. Le tre Tanga ottennero immediato successo e vennero vendute in tutta Europa. Ricordo che l'autoradio Tanga era un accessorio alla moda che veniva installato nella mitica 500 FIAT e nell'altrettanto mitica Citroën 2CV. © IK3HIA 2025. |

![]() Mini removable car radio in FM range (88 - 105 MHz) that uses two BF424 germanium transistors and a µA3089PC integrated circuit, an AA119 diode, a 5.6 V zener diode and a BA102 varicap diode. The Intermediate Frequency (ZF/IF) is 10.7 MHz. The car radio could be used in the car via a special adapter connected to the 12 V of the battery which also incorporated the Audio amplifier, and which supplied the Tanga with power and the antenna signal via a 4-pin contact block. The small car adapter-amplifier used a TBA810AS integrated circuit, mounted on a heatsink, which could deliver a power of no less than 5 W at 13.8 V. The amplifier had to be connected to the car antenna, to the positive (+12V) of the battery, to the negative (car body) and to a 4 OHm speaker (10 W). The radio could also be listened to at home using another adapter (A544) that had a mains power supply (220 Vac 50 Hz), a whip antenna and a built-in speaker. Voxson Tanga FM (green) - Voxson S.p.A. - Rome, Italy - 1970. (For more information on Voxson see this link). Mini removable car radio for the FM range (88 - 105 MHz) that uses two BF424 germanium transistors and a uA3089PC integrated circuit, an AA119 diode, a 5.6 V zener diode and a BA102 varicap diode. The Intermediate Frequency (ZF/IF) is 10.7 MHz. The car radio could be used in the car using a special adapter connected to the 12 V battery which also incorporated the Audio amplifier, and which supplied the Tanga with power and the antenna signal via a 4-pin contact block. The car adapter-amplifier used the TBA810AS integrated circuit which supplied a power of 5 W at 13.8 V. The amplifier had to be connected to the car antenna, the positive to the + 12 V battery, the negative to the bodywork (ground) and to a 4 OHm speaker of at least 10 Watts. The radio could also be listened to at home using another adapter (A544) which had a mains power supply (220 Vac 50 Hz), a whip antenna and a built-in speaker. The small car radio also came with a leatherette case to store it in once it was removed from the car mount. The dimensions of the Tanga were really tiny: 2.8 x 1.6 x 1 inch, and the weight was only 2.4 oz. Voxson sold the tiny removable car radio in three models that differed in reception range and color: Yellow for Long Waves, Red for Medium Waves and Green for the FM range. The three Tanga achieved immediate success and were sold throughout Europe. I remember that the Tanga car radio was a trendy accessory that was installed in the legendary FIAT 500 and the equally legendary Citroën 2CV. © IK3HIA 2025. |
