Locate two (2) 47-pF multilayer capacitors (47 or 470).
[ ] Install 47 pF at C2 and solder.
[ ] Install 47 pF at C4 and solder.
[ ] Find a 56-pF multilayer capacitor (56 or 560). Install at C20 and solder.
[ ] Find a 220-pF multilayer capacitor (221). Install at C7 and solder.
Locate two (2) 1000-pF multilayer capacitors (102).
[ ] Install 1000-pF at C15 and solder.
[ ] Install 1000-pF at C16 and solder.
This completes installation of the 11 multilayer caps. Remember to take frequent breaks
while building your kit to avoid fatigue.
The last six (6) capacitors in the kit are electrolytic.
Electrolytic caps are polarized and
must be installed the correct way in order to work. Each capacitor's plus (+) mounting
holes are noted on both the circuit board and parts placement diagram. If the markings on
the capacitor body are unclear, the plus (+) lead is always the longer of the two.
Locate two (2) 1-uF electrolytic caps.
[ ] Install 1 uF at C23 and solder.
[ ] Install 1 uF at C28 and solder.
Locate two (2) 10-uF electrolytic caps.
[ ] Install 10 uF at C30 and solder.
[ ] Install 10 uF at C31 and solder.
Locate two (2) 100-uF electrolytic caps.
[ ] Install 100 uF at C8 and solder.
[ ] Install 100 uF at C9 and solder.
This completes installation of all capacitors. Before moving on to the next phase of
construction, check the polarity of each electrolytic one more time to confirm all six are
installed correctly.
Identify the 1N751 zener diode--the only diode supplied with the kit. Like electrolytic
capacitors, zener diodes are polarized and must be installed the right way. Diode polarity
is indicated by a black band located at one end of the glass body.
[ ] Install the 1N751 at D1 so the banded end corresponds with the band marked on the
PC board (toward U1). Solder.
