The resistors used in the kit are 1% tolerance metal film. They are
marked with 4 coloured bands to identify the value. However it is
sometimes unclear in which direction the bands should be read.
Therefore, we recommend that the resistors be identified with a
multimeter.
Please note the fuse will look like one of the pictures below. It can
easily be confused for a capacitor. It is a self-resetting fuse.
3.4 SPECIAL NOTE - IMPORTANT:
Please note that several components can be possibly mounted on
either side of the PCB, and white component print for the part is on
both sides of the PCB. This is to offer maxiumum flexibility of the
kit: For our clear cases, most components will be soldered on the
top (tube) side of the PCB, so they are visible on the finished clock.
However, for the Viso case and for customers making their own
case, it is possible to mount some of the taller components on the
bottom of the PCB, so that the PCB can fit inside a case with the
tubes protruding. Please follow carefully the instructions. Unless
specified otherwise, please solder all components on the top of the
PCB.
