2.5.2. Either lead of the fuse may be inserted in either hole its location.
2.5.3. Turn the board over while holding the relevant component in position and bend the leads
slightly outward to hold the component in place. Solder the leads to the contact and trim the excess
lead wire above the solder joint.
NOTES:
•
To make sure that capacitor C7 and diode D1 polarity is not mistaken.
•
To make sure that integrated circuit U1 (LM7805) is not mistaken with transistor Q2
(IRF840) and diode D1 (1N4004) is not mistaken with diode D3 (UF4004) because they look
like similar.
