I picked up one of these Tice units a couple weeks ago. An oddly shaped unit that is a transformer to condition the electricity for the system. Guy let it go free because he did not want to repair the mechanical damage and broken solder joints caused by the failure of the rubber isolation mounts used to mount the transformer in the cabinet. It is a large transformer, about 60 pounds: Fortunately it looks like the damage was to the rear of the unit, pulling the wiring loose on the front but not damaging that end of the unit. Since the unit will increase the voltage 10%, reduce the voltage 10% or supply the voltage as it comes in, with or without the capacitors in the circuit, it was not too difficult to use a meter to determine how the wiring should be hooked up. The fellow I got this unit from provided a pdf of the manual which showed how the switches should be set for these different outputs. If this unit makes the system sound better, I will replace the outlets with something better than contractor grade units that allowed me to get this thing to work. This is how the rear looks now: I guess other than listening to the system with the unit, the future changes to it are to replace the isolation mounts (lots available on-line), improve the connection at the switches (solder instead of crimp-ons) and improve the lights. Right now the unit has two bulbs that have slightly different output levels but I would like to have an evenly lit meter. Runs on ~12 volts if there are any recommendations. The bulb mounts can be changed. Here is a link to some info about this unit. http://hifishack.com/tice.php I have removed the Titan accessory pigtail as I don't know if I will find one of these to add to the Power Block. It is easily replaced.
