 Learn to solder an LM386 amplifier.
+Order of Build:
+  *Resistors
+    * 1K (brown-black-red)
+    * 4.7k (yellow-violet-red)
+  * IC socket
+    * Orientation isn't critical, but should be observed
+    * Note that pin 7 doesn't have a solder pad. No need to solder it.
+  * Ceramic capacitors (C1 & C4, both 0.1 uF)
+    * No orientation
+  * 3.5mm jack
+  * External connection pins
+    * A+/A- (audio input?)
+    * +/- (power)
+    * S+/S- (speaker)
+    * Cut the pairs of pins off of the 6-pin strip
+    * Solder in one pin, adjust fit if necessary, and then solder in the other.
+  * LED (D1)
+    * Long lead toward the triangle, short lead toward the line
+  * Power jack (J3)
+    * Solder one pin, adjust, solder the other two
+  * It may be in your best interests to insert the LM386 into the IC socket at this point. The caps & pot make it difficult to insert if present.
+  * Electrolytic capacitors
+    * Long lead positive.
+  * Potentiometer
+    * Cut off the anti-rotation tab
+    * Solder one pin, adjust, solder the other two.
