I purchased it some time ago when I was more involved in the hobby, however I never used it much and it has been in my closet since then. Up for bid is a very nice Astron power supply. It's in what I would call excellent or better condition, cosmetically there are no scratches or mars anywhere that I can see.
As you can see it is the dual meter version. If you're looking for a nice USA mfg power supply in great condition at a good price you won't be disappointed with this one. Functionally, I tested it with a small that I had and it is fine.
