Just a note of caution if you're ever considering buying a tube tester on Ebay. If the seller doesn't include pictures of the case, it's not likely because they just "forgot."
This is a Hickok 800A with the guts on my workdesk. On the bright side:
1) I got this for cheap.
2) The faceplate is dirty but otherwise in excellent shape with no scratches, wear marks, etc.
3) Waiting on delivery of a few parts from Mouser. If this operates and calibrates well once they're installed, then it's worth putting some effort into the case. If not, there will be a lot of Hickok 800A parts appearing on Ebay shortly.
I can make more selling off the reusable parts than I paid for it if it comes to that, but would prefer to have a nice, fully functional tester.
4) I like challenges. Well, to an extent. Not sure of the exact point that a challenge becomes a PITA. This may define that point. LOL!
I'll post 'after' picks when I get done with it. Hopefully within the life span of most of us here.
