  • Nuvistors
  • The nuvistor was developed by RCA and it was first introduced in 1959. Nuvistors were the latest tube development at just about the same time as the introduction of the first integrated semiconductor circuits. A nuvistor is a miniature vacuum tube in a thimble sized metal case.
    Nuvistors were also produced in Europe (by Philips/Mullard, Siemens and Lorenz) and in Russia.
    Tektronix used nuvistors in the front-end of their oscilloscopes in the 1960's.
    Neumann used the 13CW4 triode nuvistor in the famous U47 and U48 mics for a while when the Telefunken VF14 pentode wasn't available anymore. AKG used a 7586 nuvistor in the C-12A mics and a RCA 7586 nuvistor in the C61 mics.
    The first nuvistor to be produced by RCA was the 7586.
    Musical Fidelity used nuvistors in their Nu-Vista 300 amplifiers and their Nu-Vista 3D CD players. Only 500 pieces of each were built.
    Conrad Johnson used two 6CW4 nuvistors in their HV-1 and HV-2 Phono pre amps in thePhono pre amps in the 1980's।
