Now go thru and solder the 8 leftmost pins that stick out from the holder. The three rightmost pins are thinner and closer together so they are tougher to solder. Luckily they are not used and you simply skip them (although the photo shows them done)
Check that you have no solder bridges - the pins should not be soldered to the metal body of the holder or to each other

Next, we will solder all of the many resistors. The 10K resistor R6 is first.
Form them into staples (as shown left with a 100 ohm resistor), then place them so they sit flat against the PCB, in the correct locations. Resistors don't have polarity so they can go in 'either way' and work fine!
Once placed, bend the leads out so the resistors dont fall out

Solder the leads to the pads (metal ring) by heating both with the side-tip of the iron for 3 seconds and then poking in a bit of solder

Use your diagonal cutters to clip the leads off just above the solder joint

Finish up the resistors by placing '''R8''' (100Kohm), and '''R7''' (1.5K)

Next is the 0.01uF ceramic capacitor '''C8'''. The tricky part here is that in older kits there are many 0.1uF ceramic capacitors in the kit that look identical to the 0.01uF!
The way to tell the difference is look for the '''103''' printed on it. If it says '''104''' then it's a 0.1uF. Make sure it says '''103'''! This capacitor forms the output low-pass filter for the audio so its important to have the right value.
Lately I have been shipping kits with ''axial'' (long-ways) package, not ''radial'' (side-ways) package. These are longer (see left) and are easy to bend over for soldering. This way there is less confusion. Either way, try to spot the '''103''' marking

Place the capacitor right next to '''R7'''.
Ceramic capacitors are non-polarized and can go in 'either way'
