TRIMMERS
The bias trimmers come next. The two trimmers have different values, so you’ll first need to identify
them by the code on the side of the case. The text is laser-etched rather than printed, so if you have a
hard time making it out, you can hold it at an angle to a light source and it should be much easier to see.
The 100k trimmer for Q2 BIAS is marked
P 104
, while the 10k trimmer for Q3 BIAS is
P 103
.
The two trimmers can be soldered like normal components, by bending the legs outward as shown:
These trimmers are used to bias the germanium transistors. We will adjust them at the end once the
pedal is fully assembled.
