NAD 1020 forforsterker

Selger en NAD 1020 forforsterker. Dette er vel mer eller mindre forforsterkerdelen du ellers finner i legendariske NAD 3020.

Testet den idag, og alt fungerer som det skal. Jeg har renset potmetre og brytere.

Utseendemessig ser den bra ut med bruksmerker man må regne med på utstyr som er passert 40 år.

Pakker og sender gjerne hvis det er behov for det.

Notes

A Stereo pre-amplifier, the same as the pre-amplifier section in the integrated NAD 3020 Series 20 Stereo Amplifier.

With RCA input sockets for Phono (MM), Tuner and Aux, input/output RCA sockets and DIN socket for Tape and a Phono Input Capacitance Selector switch (100pF, 220pF, 320pF). Output sockets for Pre-out and High-Level Pre-Out. Some models have three AC outlets and some have a voltage selector.

Rotary controls for Bass, Treble, Balance and Volume, push buttons for Power, input selection (Aux, Tuner, Phono, Tape), Audio Muting and Loudness. Power On pilot light and jack for headphones. Rack mount handles are an optional extra.
