About V76s
The ultimate tube microphone pre-amplifiers was designed by the Insitut fur Rundfunktechnik and built from 1958 basically by TAB/Germany (Tonographie Apparatebau, Wuppertal/Eberfeld). This company also built other units for this series, as the and 72a (low/mid gain preamp) and the U73 (tube compressor).

Engineering standard and technical quality at this time was so high, that it would be impossible to build this preamp today for its current market price.
The V76 was designed for applications where the "standard" V72 could not provide enough gain (ie for dynamic mics) and where it was essential to have a switchable variety of gain steps plus some selectable high and low frequency pre filtering. The circuit of the gain selector works in a quite unique way of combining variable input attenuation and variable feedback. This results in very good noise figures at all gain settings.
There are 3 controls at the front panel: The 12 step gain selector (+3dB up to +76dB), a 3 kHz rolloff switch and a four step low cut filter.
The unit is fully self contained, it includes its own 220V power supply and all connections as the mains supply and the balanced input and balanced output are accessible through a single 12pin Tuchel connector. The high quality balancing transformers at the signal input and output and the mains transformer are shielded with multi layer mumetal/copper technique. Pentodes Telefunken EF804S and E83F used in the V76 are common types and are still easily available.

OTHER V76 VERSIONS:

1. V76/80 - with switchable lowcut at 80Hz and 300Hz.Fixed input filter 40Hz and 15kHz.
2. V76/120 - with switchable lowcut at 120Hz and 300Hz.Fixed input filter 40Hz and 15kHz.
3. V76u - a special version with switchable three position filter low cut filter at 80Hz 120HZ and 160HZ.Fixed input filter 40Hz and 15kHz.
4. V76m - M is for 'Messverstaerker' a special version without switchable low/highcut and without fixed input filters; linear frequency response from 20Hz to 20kHz
5. V76s - S is for 'Schallplatte' a special version with internal lowpass filter for Studio Lathes

If you are lucky enough to own a V76 it will probably be a V76/80 or the V76/120 type. The IRT designed this versions for Radio and TV Studios, where it was important to cut off any noise in the studio below 40Hz and above 15kHz. If you are using yours in your TV studio this will be fine, but most V76s are used in top class music recording studios today. Obviously it makes no sense there to limit the performance of this terrific amplifier! So make sure that yours has been modified to give you the full frequency response.
If this is done right, the V76 has an impressive response from 10Hz to 35kHz , +/- 0.5 dB !!)
