Walthers Operating Oil Pump

The walther oil pump instructions say to power this accessory to use 8 volt DC.

All my power is PostWar ZW or 180w PowerHouse - all AC.

Can someone recommend a simple power solution for this accessory. I have 4 of them.

thanks in advance

Just buy a small used HO transformer. They can be found for under 10 bucks at train shows.

Or use a rectifier.

Go to Radio Shack for a small DC transformer.
