□
Install the 1N4732A Zener diode in location D1.
If you can’t read the part number on the diode, D1 is
larger of the glass bodied diodes. Be sure to
correctly orient D1 so that the band on one end of D1
is on the same end as the stripe on the board.
□
Install the five 1N4148 diodes in locations D2, D3,
D4, D5 and D6. Again, make sure the band on one
end of each diode is oriented as shown by the stripe
in the part outline on the circuit board.
□
Install the 470 Ohm resistor in location R1.
□
Install a 220 Ohm resistor in location R2.
□
Install the 100 K Ohm resistor in location R3.
□
Install 1K Ohm resistors in locations R4, R5 and
R6.
□
Install the 2N7000 MOSFET transistor in the
location marked Q1. Be sure to orient the flat side of
the transistor as indicated on the circuit board.
