Boy this is tempting to me....for nostalgia.
In my garage is a Kenwood 5400 I bought back then as part of my first real stereo system. It had a 4ch switch on the back but I didnt know what quad was and was told to ignore it. 35 watts per channel but it sounded good to me. I wonder if the capacitors are still good.
Someone I worked with later on had a model 9500 but I could not afford the higher powered ones back then. Similar look to this one with the wood side panels.
