Descrizione

This is a preamp DIY kit with a phono equalizer and a lot of great features. Precision phono stage RIAA equalization (CR not NF) supports both MM and MC cartridges. Two low noise OPAMPS (NJM2068DD) are used in the phono equalizer amp circuitry. OPAMP preference are accommodated by use of socket mounts allowing easy substitution of alternative OPAMPS.

Two 12AU7 (ECC82) tubes are used in the line amp stage. Gain is switchable (Approx 1x to 3x). Reduced hum/background noise circuitry includes a low flux leakage R-core transformer, a FET ripple filter for B-power and the tubes are powered by the DC power supply.

Sufficient space has been provided on the PCB for substitution of larger coupling capacitors. Support for 4 different voltage environments including Australia (set during assembly). Ideal complement to TU-8200 power amp.
