Eight, IV-17 or IV-4 display tubes are NOT INCLUDED! They are inexpensive and easily available on eBay and elsewhere. A good quality, 12v power supply is also required. Everything else is included. The case is optional.
All word clocks include surface mount parts. They are easy kits to assemble if you have previous experience working with SMD/SMT. To successfully assemble this kit, you must have a good quality temperature controlled soldering iron, tweezers, solder wick, magnification, the usual tools, and steady hands. Otherwise, this kit is not for you.
