I have some old 240V-120V step-down transformers, and I am wondering if I could connect two in series to get 120V-30V? The first one would go from 120V to 60V, then the second one would go from 60V to 30V. Is there any reason why this wouldn't work?
I'm trying to make an adjustable power supply, and this would be the power source.
