5. Jumper wire: Use one of the leads that you just clipped off of the big electrolytic capacitors (C9,
C10, or C11) as this jumper. Use your needle nose pliers to bend the lead in the shape of a
staple.
20
Install the jumper in the holes and solder the leads.

6. Bridge rectifiers (Part # BR1, BR2): Bridge rectifiers have 4 leads and it is very important to make
sure each lead goes in the correct hole. The only indication on the circuit board of how the
rectifiers should be oriented is a square pad. The positive lead (the longest lead
22
, labeled with a
“+”) goes in the square hole
23
. The other leads should line up properly with the other holes.
a. Install both BR1 and BR2 with this orientation. Solder and clip the leads.
b. Before moving on, double check the orientation of the bridge rectifiers. Make sure the “+”
and “-” printed on the component are in the same orientation as the “+” and “-” on the circuit
board.

has “+” signs where the positive (longer) lead goes. The negative side of the caps have white
stripes pointing to the negative lead.
d. Install all of the smaller electrolytic caps (C2 ,C5 ,C8 ,C12). Solder and clip the leads.
16
e. Now install the three big electrolytic caps (C9 ,C10 ,C11).
17
Solder and clip the leads
18
, but
put one of these clipped leads aside for use in the next step.
WARNING:
The big electrolytic caps (C9 ,C10 ,C11) are likely to explode if they are installed
backwards, which could result in personal injury. Install in STRICT CONFORMANCE with
these instructions!
f. Before moving on, double check the orientation of each of the electrolytic caps. Make sure the
stripe on each electrolytic cap is in the same direction as each cap in the picture.
