Philco 7020 3" portable scope

Thanks. It's slowly coming along. The hardest part was getting the hardened rubber bezel of the CRT without breaking anything. I liberally applied some ArmorAll and let it soak in for a few hours. That softened it up just enough.

What I thought was dirt turns out to be phosphor loss


Then, I had to unmount every control to get the chassis out!


At last the fun can begin
I scanned the instruction manual and uploaded it here

Cool Find!
