EDC Model 521 Programmable DC Calibrator Untested For Parts Only [18-.5]

Description

Came to us with a piece of paper that says "does not work." We aren't experts with this stuff, so we are unable to diagnose or repair this beauty. Something was rattling around inside the case, so we opened it up and removed a loose heat sink and a component as shown in photos. We also included some random components that came with it because why not. Sold for parts with no guarantee of functionality. No cords or cables included. You'll have to repair it yourself if you want it to work.
We're a surplus store, and we aren't experts with most of this stuff.  So, we don't make any guarantees beyond what's stated in the listing & pictures.
Feel free to contact us with any questions!
