STEP 8: Add the internal trimpots. Many people get confused by these because the
trimpot itself only has 3 legs, but the PCB has 5 holes. The PCB has 5 holes so that it can
accomodate a variety of different trimpot brands and models. There should only be one
way each trimpot will fit into the PCB without having to bend the legs.
MIN trimmer
: This trimmer will affect the amount of minimum distortion. Originally it
was a 51k resistors, so setting this trimpot to exactly halfway will give you stock TS808
specs.
MAX trimmer:
This trimmer will affect the amount of maximum distortion. Originally it
was a 4.7k resistor, so setting this trimpot to exactly halfway will give you stock TS808
specs.
LOUDER trimmer:
This trimmer affects the gain of the second half of the op amp.
Originally it was a 1k resistor, so setting this trimpot to just shy of full turn counter
clockwise will give you stock TS808 specs.
