Mike.......It took me about an hour from start to finish. There is no soldering, everything is pin connectors, and a small power supply board that gets installed on the bottom side of the amp above the power supply board on a short stand-off. All the work can be completed with a phillips head screw driver and a 1/4" nut driver. The kit includes the LED power supply board, the LED light strips for the two meters, new filters for both meters, and a LED light strip that replaces the lamps for the lower back lit writing. The directions are fairly clear, although they did not explain that the wiring harness from one meter LED strip plugs into the circuit board on the other meter LED strip. The directions also tell you to reinstall the front panel before you connect two pin connectors from the LED power supply board and the lower LED strip. I had to remove the screws from the front panel bracket after reinstalling them, so that I could move the front panel out far enough to get my hand in there to plug the pin connectors in, then reinstall the front panel bracket screws. The installation is straight forward with those two exceptions. The hardest part was turning the amp upside down to get at the screws for the front panel mounting bracket, and then geting it turned back right side up once the work had been completed. You don't want to put any weight or stress on the front panel glass. The MC352 weighs 107 lbs. You don't just move it around like a preamp. Follow the directions line for line and you will do just fine. The way the amp and meters look when complete makes the effort worthwhile.
