Comment
This parallels R5 and R37 and adds R36 to the
circuit, changing the current to the op-amp.
Using the resistor instead of the wire provides
more versatility to adjusting the current in the
feedback loop to the op-amp.
Using the resistor instead of the wire provides
more versatility to adjusting the current in the
feedback loop to the op-amp. An 8.25 kohm
resistor soldered parallel onto R36 will change
R36 to 4.12 kohm.
Everything else remains at default values.
