Your kit also contains six electrolytic capacitors.
Electrolytic caps are polarized
and must be installed the correct way in order to work.
The capacitor's plus (+)
mounting hole is 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 three (3) 1 uF electrolytic capacitors.

This completes capacitor installation for now. Take a moment to double-check
capacitor location and electrolytic polarity. Electrolytics
must
be installed
correctly in order to work. Also, note there are several fixed-value capacitors
remaining in your kit. These will be installed later as
frequency-determining
parts. Finally, the VXO variable capacitor (C16) and adjustable trimmer (C1)
will be installed last because of their larger size.
Now that you've accumulated a collection of nipped-off lead-ends, this is a good
time to install the board's five (5) jumper leads. Each should be pre-formed prior
