This is an old pic of my system (before the roof fell...)Top left is the ALC-20,under is one of my Altec 6X9-4A connected as separate Mid and Tweeter on a separate 4ch amp (TAN-220) the latest version of that box has a double Altec 6X9-4A with the mids and tweeters in series because they are 4 ohms each, then we have the Audio Control R-130 !/3 Oct Graphic EQ, under we have the Sound Shaper Three EQ and on the bottom is the Sony TAE-7B preamp. Next row top right a Sony TCK-??? (sold it) and under is a TCK-890ES and under a CDPC-90ES 10 disks CD player (I also have the 10 CD changer for the car) on the bottom is my TAN-7B VFET amp and next to it is my PSX-700 Turntable. On the other box(not shown is another double Altec 6X9-4A in a box and also a TC-377 next to it.
