If anyone is interested I just picked up a NOKIA phone charger ( Wall Wart Transformer ) for $1 at the local thrift store. It shows the output as 3.7v.DC at 350 m.amps. When I metered it the voltage was actually 8v.DC. It works great for powering 12 Tortoise switch machines on my HO layout. They are quiet and operate at a moderate speed.
Just my 2cents. worth.
Limey.
Is the 8 volts while the Tortoise is running or is that no load voltage?
Many run the Tortoise at 9 VDC and like the slower point movement.

That's 8v DC no load voltage. I have a 4 way crossover where all 4 machines operate simultaneously and they all work just great. I don't forsee any time when I would operate any more machines than that at one time. Sequentially yes, maybe.
I am curious as to what the actual DC voltage is when operating. The current rating is just fine for the Tortoise. They are low current devices. Good find.
I see questions in different forums quite often on what voltage to operate the Tortoise.
