Genuine VU DUO during recent repairs I noticed a variable resistor located on the Power Supply board, I am curious to know what it is there for and what is it exact function. Obviously there to adjust one of the outputs from the PSU but I would like to know which one??

If you are tecnical and have multimeter.
then you can put the meter and slowly move the variable resistor and see if the output change, PS make sure u note the position of the variable resistor be 4 u move it.
Please its allways dangerouse our power supplly circuits, if u dont know what you doning DON'T DO IT.
