This is a nice, hard to find, States Multi-Amp.  They don't make them like they used to.  Don't know much about these.  It is solid, well-built, and ready for your testing business needs.    Get this before someone else does.....

input 120V //   Output 0-5000 VDC   //  Comes with what is pictured.  Pretty good shape for its age.  some minor scuffs and dings, but overall solid.

Made in Dallas, Texas
