I bought a transformer today which I have rewired and will give to any of our British members who would like to pay the shipping cost.
It is an Alderman “A” Transformer, rated for 200-250 volts, 50-100 hertz, 70 watts. It looks to be prewar and made in England. It is about 4x4x5 inches in size. It can be used for 4-12, 6-14, or 10-18 volts, but stepped in the typical prewar fashion in 5 steps. It has a 13-ampere BS 1363 plug with a good 3-ampere BS 1362 fuse in it. It has banana jacks for the output connections; and the original plugs are included. I have replaced bad internal wiring and the flex (power cord). The new flex has American wire colors (white, black, green, not blue, brown, green-yellow). The case is connected to the protective earth (equipment ground). The transformer was set up with a fuse wire, which I replaced with an internal 5-ampere auto-resetting circuit breaker.
It might not be the best thing for running trains, because of the e-unit-tripping gaps in the switch; but it may have some use for accessories.
