Hi
Hobbiest electronics shops usually have cheap 12 volt(nominal actually 13.5") volt 3-10 amp supplies for people who enjoy building their own circuitry. The 12 volt nominal thing is due to these supplies being derived, essentially, from 12 volt battery charger designs(you need the higher voltage to "push" through a battery's internal resitance and leave a 12 volt charge).
As a note: watts=volts x amps. Thus, a 12volt, 3amp supply is 36 watts of power.
This is plenty for all rtrs on a two lane track.
You need to note on the specifications" Filtered and regulated". And it is easy to just attach the pack to your old plugs to keep your configuration unchanged.
Fixed supplies are usually cheaper. One problem with adjustable supplies is that the dials are not particularly accurate ("mine goes to Eleven") So, to be sure you get the same thing every time, you have to adjust with a separate volt/ohm meter(available from the same hobby shop).
