This is what you start with-- the complete kit including enclosure, hardware, and a detailed instruction manual. The WM-2 kit is not difficult, and will take the average builder approximately 4 hours to complete.
Here's the completed circuit board, before attachment of the connecting wires. Note that the two toroids are large and have only a few turns-- no problems even for a beginner. All component and connection points are silk-screened on the board, and the solder side is masked for your convenience.
Everything fits neatly inside the WM-2 case, which is pre-punched to very precise tolerances. Alignment is simple, using a Digital Voltmeter, and there are only a few adjustments to make. An RF source is NOT required for alignment.
Ta-daaaa! The finished product, a laboratory quality instrument and YOU built it!
