Some pictures

Sorry that you can't really see the TV, just the screen. It's currently hiding in a corner of my apartment that is entirely too full of stuff. These are with no restoration, I haven't had a chance to pull the chassis and mark down electrolytic cap values.

Note: The random breaks in the picture aren't on the TV screen, they're cables that are in the way.

First, a couple of the set displaying broadcast TV (via a DTV converter box):
TV#1
TV#2


Now, a couple test patterns. These were generated using a B&K 1248 test pattern generator.
Grid of lines
Dots (closeup)

Given that the set is unrestored and almost 50 years old, I think the picture is fairly decent. I definitely intend to replace all the electrolytics, hopefully that will improve the blurriness and ghosting (the ghosting is most visible in the closeup of the dot pattern - these are nice round dots on my 90s RCA XL-100). One quick question - is there anything I need to do differently discharging the CRT on this set versus the solid state sets and computer monitors I've worked on in the past? My usual procedure is to take a plastic-handled screwdriver with a wire attached to the metal part, clip the wire to the rake/spring/whatever touches the aquadag on the tube, and touch the point of the screwdriver to the anode connector.
