trimpot 
noun
A small potentiometer used to make small adjustments to the value of resistance or voltage in an electronic circuit.A feature of this PSU that greatly impressed me was that you could rotate a trimpot inside the PSU to adjust your 12V and 5V rails....
- Next I decided to have a play with the trimpot inside the unit.
- After poking around a few minutes I found that the trimpots adjusted the bias on the transistors.
