This receiver is well loved we brought it back as far as we could. Installed LEDs cleaned controls and got it up and running again. There are some push buttons missing and some non-original flip switch knobs. A new power switch was installed along with a new power cord. The -20db switch sticks a little but functions properly. It's a bit banged and bruised but it's a rare bird and has a fantastic phono section. Would be great for spinning records or streaming your favorite music. This is a great machine produced by Sansui and is looking for the right place to call home. Power output: 110 watts per channel into 8Ω (stereo)Frequency response: 10Hz to 30kHzTotal harmonic distortion: 0.2%Damping factor: 10Pro packaged, insured and includes tracking. Everything photo'd included. No PO Boxes. Thank you.
