Hi, this is a excellent functioning and sounding NAD Model PP-1 Phono Preamplifier. It comes with the adapter, and it has a Power On Light, and grounding screw. Great NAD quality.
If you have a vintage turntable, but your amplifier or receiver does not have a Phono stage, just plug your vinyl spinner into this and then out to any available RCA inputs such as tape, CD, Aux, ect., and you can enjoy your turntable without having to buy a vintage receiver.
Just $30, please email, call, or text to come and check it out, thanks.
