8.5”X5” replica 1 TE silk screened PCB with expansion male edge
Tools required for assembly:
Soldering iron, solder, wire cutters, needle nose pliers, and a multi-meter
Before you begin:
Make sure you have proper working space and that you heat your iron before beginning the assembly. This kit
is not for beginners and Briel Computers assumes that you have some prior experience with soldering circuit
boards. If you have never soldered circuit boards before or don’t feel you are ready, you should build other kits
of a smaller, less complex nature before building your replica 1.
Reading and identifying resistors:
In previous revisions of the replica 1 kits, all parts were labeled in an effort to make it easier on the kit builder.
Now, the manual is being expanded to help newcomers to kits learn to identify the parts and read their values.
Resistors have 4 colored bands on them that are used to identify the value. The first 3 are the value and the 4
th
colored band is to identify the tolerance of the resistor. The 4
th
band is usually silver for 10% or gold for 5%
tolerance. Here is how to read the other three to get the value:
Figure 9: Resistor color code chart
Let’s assume the resistor you are trying to identify has the colors orange, and then another orange, then a red
band followed with a gold band. So, to read the resistor, find the gold or silver band, that identifies the 4
th
band.
Hold the resistor so the 4
th
band is on the right side and read the first color on the left.
