Connecting 12v lights in serial

Yeah, I think modern power supplies generally use a linear regulator to keep the voltage steady.

Yeap, and as @XG BC said, the modern switching power supplies are even better; efficiency (= heat generation) wise. It's simply a matter of taste. 

I simply like the hum of, e.g., the original LEGO power supply for 9750 (or that of my 99er which sits on a 230/110 voltage converter, again I chose a transformer - transforming 230 to 110 to transform 110 to whatever the TI needs ...)

It will all work out.

Thanks, this is super useful. I might grab an additional transformer and check the connectors (spread the out slightly for better connection).

Replacing cables is a last resort for now, as I've nicely hidden most of them with light gray 2x3 + 1x2's along side the tracks
