Z4000: how to determine date of manufacture

Jeff2035OGR Forum Member

A friend asked me if I knew how to tell when a Z4000 transformer was manufactured.

I don't know.

Is there a way to determine this?

Also, have any changes ever been made throughout the numerous production runs?

I purchased two about 10 years ago and they are great.
