Vintage SONY surround sound system TA-N55es surround sound amp 
 
This came from a multi-million dollar house in Florida. I got it in trade for recording studio time. They are highly rated component Hi-Fi Stereo gear.  
I have tested all of the amp/ channels and they are all perfect. 
I have two of these available. 

Listed directly below are the other amps and a surround sound receiver for sale here on ebay, so please see my other auctions!

Sony TA-N55ES 
The Sony TA-N55ES power amplifier is solidly constructed and has detailed sound. The two-channel amplifier can power two speakers at the same time or the two channels can be bridged together to provide more output to one dedicated channel. It is 110 watts per channel in stereo or 300 watts in mono. It has an output control and can be directly hooked up with an iPod. It was made to accompany the TAE-1000ESD Dolby-Pro Logic preamplifier and could be complemented by the small TA-N110 as well. Audio outputs include banana plugs jacks, raw speaker cable jacks, and stereo L/R RCA.
