 +As the U output runs much hotter than X, Y and Z, the U LED is also much brighter.  
 +To balance this, it is a good idea to use a larger valued resistor for U LED's RL (current limiting resistor). typically 2-3 times the value of the other three. For red/blue bi-polar LEDs, usually 4k7 is a suitable value for RL, so for U's RL try 12k or even 15k. Which RL is the one for the U lED? It is the one near the left edge of the PCB (power pins at the top), next to the two 270k resistors.
