The 6021 is powered by a transformer which is 16 VAC. Usually, with reduced load, the voltage is 5 to 10% higher. To make matters worse the voltage is rectified which means that the peak voltage is 16 x square root of 2 = 22.6 V or even higher as explained above. So on a 6021-6002 couple the digital voltage could easily reach 22 volts So this may explain why your car is more luminous with this older digital circuit. Cheers Jean

I suspected it, or the other two additional coupled double deck coaches draining voltage from the first which has the destination board. Longer cars and led kits and two in each. The brightness is good, even in the destination board, but the right side is not lit. I'll try all the cars together with the 6021 test track. Fully lit up with all cars and the 6021. It's the smp power supply difference then.
