Another Westinghouse H840CK15

[trinescope]

I found this one semi-locally. Missing knobs but everything else appears to be there. I don't have a real way to test, but the getters on the CRT at least appear to be OK. I'm going to try to get this thing working little by little starting with the horizontal sweep section and go from there. Lots of paper/wax capacitors in here! You all think I should try to maintain appearance and restuff the paper caps or just say screw it and put the modern yellow ones in there? I don't see where any components have been changed on the bottom of the chassis, and most of the tubes appear to be original Westinghouse (mostly rebranded RCA and GE) except the horizontal output tubes and one 5U4. One question: Is the chassis copper plated or is it just some sort of copper colored coating?

Serial number MW005779, chassis number ME000552
