CLEM K,
I see that Guns has corrupted your thinking, you can due the same thing with an old ZW and still adjust the power input with the handles of the ZW. Although the Z4K must be reset after the power has been turned off by lowering the handles, the old ZW's or KW's start right up at the needed Voltage each and every time. Then if you want to vary your voltage input for say additional switches, you still have that option also. Trash the Bricks, or better yet sell them to Guns.
