Any clues as to the AMPs that it draws?? I do have a 14V AC transformer which on a takeoff Leads I could fit a resistor to bring the VOltage down to desirable. TA in advance Nev PS: do not really want to use the Blue or White Controllers as a Source.
		NOt wearing the Pink Pinny, which is hard to see and now I have a white Pinny which also is hard to see against MY pure white Skin Still have 2 new shiny tin Hips that is badly in Need of Repair matching rusting tin shoulders and a hose pipe on the aorta Junior member of the Banana Club, a reformist and an old Goat with a Bad memory, loafing around

As the crane uses LFCM motors, the rule of thumb would be 10VA per motor, 1VA for each of the lights, and goodness knows what for the magnet, but say 5VA.

But please do not change the direction with the knob, otherwise you have 24 V (too much...) I do not know if the older 451 crane had a nominal voltage of 20 V, instead of 16 V of the more recent 7051 model. Cheers Renato

Cheers Renato Thnaks Renato, unfortunately I do not have any of the old transformers with the red knob that regulates speed. I have a Maerklin 60VA power supply and also another brand that outputs 14V AC. so will give a test to see which is best. If necessary I will adjust the power to the crane by putting a resister into the circuit. N
