SOLDERING
Start with the smallest parts - r esistors and d iodes . There are three values of resistors: 2 20R (2x)
and 1 00k (2x) and 1 k (1x) - take your time and check those values
u sing a multimeter
(or you can
check the color codes if you are seasoned enough). After soldering snip the leads close to the PCB
(be sure to make this step on all remaining leads in the course of this guide).
Solder also the d iodes . There are just two values of them: 1 N4007 - the bigger one (1x) and 1 N4148
(1x). Be careful, d iodes are polarized ! make sure that the marking ring on the diode body matches
the marking on the circuit board.
