Vintage Sansui 661 Stereo Receiver in LED Upgrade Serviced - $225 (Williamsburg)

Sansui has long meant innovation and excellence in sophisticated audio electronics.
I have serviced this unit by cleaning all switches and knobs with Deoxit.
All controls are noise-free.
I also upgraded the bulbs with LEDs so this should operate for years (decades?) more trouble-free.
Thanks to a startling innovation called CBM (Circuit Board Module) developed specifically by Sansui for its finest professional studio equipment, you can forget about price and concentrate on the outstanding Sansui quality and performance of the all-new 661.
This is a stereo receiver that delivers expensive tonal quality and performance.
Its power amplifier is of a very advanced all-stage direct-coupled OCL design providing RMS continuous power of 27 fully usable watts per channel (total music power 110 watts) with a surprisingly wide power bandwidth of 15 to 40,000Hz with very low overall distortion Its MOSFET equipped tuner and highly versatile preamplifier and control sections with two stereo tape record/monitor circuits.
stereo AUX inputs and much more speak to its quality and heritage.
