You need no more than an incandescent lamp. There are two rings on the spindle. The outside ring is 60Hz and the inside 50Hz. Use an incandescent bub and tune. When the ring sees to stand still, it is in spec.
If you are a PAL/50Hz region (Europe parts of Japan South America), use the inner ring. In the US, 60Hz Japan or other 60Hz regions use the outer ring.
