TC* ELECTRONIC ASSISTANCE R-390A/URR Communication Receiver Very Good Condition

I’m liquidating in a state of a gentleman that repaired CB and ham radios he recently passed away and I’m uploading all of his equipment to eBay. This unit was on his workbench and I was told by the family was working at the time of when he passed away. I have no idea if it needs realigned or if there’s specific functions that don’t work. I know that when you plug it in it lights up that’s why I’m selling it for parts as is because I’m not sure how to completely test these, but was told that this was working.
