Designed as a microphone and main studio amplifier, the V72  had a fixed gain of 34dB, and was used with a high pass filter as a mic  pre, and as a buffering amplifier to make up for losses from a passive  fader EQ. When the V76 arrived, the V72 was generally used only for  buffering in broadcast applications.\u003cbr\u003e\u003cbr\u003eIn the mid 50s both the  Siemens and TAB companies began manufacturing the units for Telefunken,  and the V72 became the standard preamp in German radio stations, while  its cousin the V72s was being used extensively by companies like Decca  and EMI. \u003cbr\u003e\u003cbr\u003eApproximately 25,000 units were built for domestic use  in Germany, and many more for export. By 1963, its reign had come to an  end, as the age of transistors had arrived, and the V72 was replaced by  the V72t (’t’ for transistor). Siemens continued to build the V72 until  1964, and the V72b until 1966. TAB continued to build the V72 until the  mid 1970s.\u003cbr\u003e\u003cbr\u003eSeveral different amplifiers were made on the basic  V72 circuit platform, including the V71, V76 and V77. Other members of  the V72 family, with different circuitry, are the ‘a’, ‘b’, \u0026amp; ‘s’  versions of the V72, as well as the V70, V74a and V77b.\u003cbr\u003e\u003cbr\u003eSiemens  had modified the classic V72 to come up with the V72b, which uses a  different pair of tubes, the E283CC and E88CC. The V72b pairs well with  the V76, with enough head room to handle its high output level. It has a  better signal-to-noise ratio and less inter-modulation distortion than  the V72, and is an excellent mastering amp.  \u003cbr\u003e\u003cbr\u003eAt the dawn of the  1960s, AEG-Telefunken was a major manufacturer of broadcast equipment,  and their systems were found in radio stations around the globe. The  venerable V72 and its relatives were an important part of these  facilities: rugged, dependable, quality units that stayed in operation  for decades, and are still valued today.Recapped, serviced, with a 1 year warranty.","brand":"Vintage King Audio","offers":[{"title":"Default Title","offer_id":44449474773095,"sku":"20721","price":0.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0658\/8848\/5479\/files\/used_vintage_king_2u_telefunken_v72a_dual_channel_rack_loaded_a5f4562b-34af-40ec-a9a1-926896b9a2b4.jpg?v=1787089095","url":"https:\/\/vintageking.mom\/products\/vintage-king-2u-telefunken-v72a-dual-channel-rack-loaded","provider":"Vintage King","version":"1.0","type":"link"}
