1/16 Bucyrus-Monighan Walking Dragline

Thanks you guys for the comments.

I have a question. Can my DX7 be powered up with 12VDC?
I will be hard wiring it into my control cabinet eliminating the 9.6VDC battery pack.
I don't want to cook it. The power supply in the photos is adjustable to 40VDC and I have it set to ~10V it is not practical to carry that thing along.
Looked around on ebay for a industrial power supply without much success. Possibly just look around at all the wall plug battery chargers laying around here, maybe I have a 9.6V one.
