Details:

Cosmetically, it is in good condition, but does show where that's to be expected for a vintage item. For sale is a Kepco HB 525M regulated vacuum tube power supply that uses 7581 tubes not included. That is why I m selling it as is, for parts or repair. This item is very heavy, that why the shipping considerable.

There are scratches, nicks, and some imperfections. Please refer to the photos for finer details, as they will do a better job of illustrating condition than words can. It came from a studio, but it is untested. I've been packing Vintage electronics for a long time, and know how to pack them properly ensure they are well protected during transit.
