This unit has been modified by Audio Dimensions in San Diego, CA. The tube cage has been trimmed to accept premium quality interconnect cables. It has also been set up with an external power supply & has a multimeter Gauge that links to the unit so you can keep your eye on things. Cosmetically this unit is sub par, but its functionality is great...
