Position of the front panel LEDs
In the 15 V3 boards the front panel LEDs were protruding a bit; this was
bringing a slight misalignment on the screw holes of the front panel and
was making the screwing of the front panel slightly difficult.
As Betty Magnin pointed out this is due to the tolerance of the body of
the LEDs and moreover to the position of the LEDs in the PCB.
Note that the position of the LEDs is exactly the same as in V1; in V1
we had not noticed any issues as by chance the assembler was
systematically pushing the LEDs to the rear when mounting them.
Betty Magnin suggested a modification of the PCB design to move the LEDs
more inside the board.
