Onkyo TX-SV373 5.1Ch 270W Dolby Digital Surround Home Theater Ricevitore con Phono
It's been cleaned up nicely and tested on ALL 5 Speaker outputs. I also ran the radio, an Aux. Yes, no preamp needed as unlike units that followed where they left a mag level input off. Surround output: 50W (front), 50W (center), 20W (rear).
