TAB V76 Studioversion

TAB V76 Tube Preamp

The classic of the West-German studio technology

The V76 was developed by the Institut für Rundfunktechnik (“institute of broadcast technology”) in the late 1950s. It replaced the universal amplifier V72 that had previously been used for amplifying microphones – which obviously was a lot less flexible, with a fixed maximum amplification of 34 dB. The V76 was built by a company called Tonographie Apparatebau (TAB), based in Wuppertal/Germany.
The V76 easily counts as one of the best microphone pre-amplifiers ever built – its sophisticated circuit design, its unparalleled build quality and the use of component parts of the highest order warrant for some excellent reproduction of sound.

Varieties
There is an entire string of variations that were all aiming at specific applications. The example for rent is the much sought-after TAB V76s variety which was originally used by the Deutsche Grammophon. The more widely used types V76/80 and V76/120 were designed mainly for broadcast use. The V76s, however, was specifically designed for recording studios –  the main difference between the individual models can be found in the more flexible design of the passive filter stage that many recording studios had been demanding for. All other specifications are identical. One crucial aspect of the tonal qualities of the V76 certainly is the very sophisticated input transducer stage which alone boosts the input signal by the factor 30.

Specifications of the V76s

  • two amplifier stages based on two valves each (types of valves used: 3x EF804s, 1x E83F)
  • complex circuit design
  • impeccable build quality
  • sophisticated design of the input transducer stage with an extremely high amplification ratio of 1:30
  • in contrast to the V76/80 and V76/120 vastly expanded frequency response from 30Hz to more than 20kHz
  • passive filter stage: adjustable high-pass filter at 30, 60, or 120Hz, adjustable low-pass filter at 8, 10, or 12Hz (at the 15Hz setting, the low-pass filter is not in use)
  • massive sound thanks to the built-in anode chokes
  • 16 dB of overdrive headroom
  • twelve amplification levels adjustable between -6 dB and 66 dB
  • complex signal path adds some subtle colouration to the audio signal (contrary to the more puristic and neutral character of the V241)
  • clearly defined and contoured tone with excellent hi-fi character
  • manufacturing start: 1958
  • weight (with/without casing) 12 / 7kg


How to use it
Since the V76 as the V241 has its roots in the golden age of radio valves, it was consequently designed to be used with valve-based condenser microphones. When using transistorised microphones, there is a risk of the V76 input transducer being damaged (or even destroyed) because of the phantom voltage that is required for the operation of the microphones. The Neumann N452i 48V power-supply helps to solve this issue, and it can be rented along with the V76 at no extra charge – this way, the preamp can be used with transitorised microphone designs like e. g. the Neumann U87, AKG's C414, or the Microtech Gefell M930. When using dynamic microphones, operation poses no hassle.

The example for rent
The example we have for rent was completely refurbished by specialist Eckehard Dux, and its technical specification is excellent, to say the least. The pre-amplifier was installed into a Lunch Box that was equipped with XLR input and output.
The V76 can also be used with line-level signals (synthesisers, electric pianos, drum computers, within a mastering chain etc.) thanks to its custom line-level cable which can be rented at no extra charge.
