□
Insert the small 2N7000 transistor in location
Q1. Be sure to orient it with the flat side as
shown in the printed outline. Carefully solder
the three leads to the board from the bottom.
□
Insert the larger transistor in location Q2. Be
sure to orient it correctly as shown in the
printed outline. The metal tab of the transistor
should be facing the silkscreened outline. After
soldering, gently fold the transistor flat against
the board as shown in the picture. It does not
need to be perfectly flat against the board; don’t
bend it sharply enough to crack the pins.
□
If you will be using the terminal block to
connect the Mini-KA to your equipment, insert
it into the board at location TB1. Make sure the
openings for the wires faces the outside edge of
the board! It will work the other way, of
course, but it might be more difficult to make
connections. You might want to hold it in place
with a piece of tape while soldering.
