Got the Sylvania!

[veg-o-matic]

Picked up the Sylvania yesterday, but didn't get it into the house until this afternoon. Nephew was helping and I noticed all 6 knobs at the bottom had fallen off at the same time. When I opened 'er up, I found out why--the chassis was bumping around inside the cabinet! I think one more good jolt and the picture tube would have been a goner.
The picture tube, by the way, must have been replaced at some point because it's an RCA Perma-Chrome Hi Lite.
The chassis is DO211, which makes the model number 25LC105, according to the SAMS.
This set has some weirdass tube sockets. They're more like just a bunch of little connectors on the PCB rather than regular Bakelite sockets. There are some regular sockets, too.
Okay, so I fired her up and the pictures tell the story. The picture actually looks focused to me, if smallish and green. The pic looks B/W, but it's really green. The first time I turned it on, the picture was more orange. The color and tint knobs don't seem to do a dang thing. I had to fiddle with the HHold knob a little to get a picture.
In poking around a little, I noticed that some of the tubes in the weird sockets were loose. This may be what the service guy meant when he said the sockets were worn out. Is there a good way to tighten these up?
Other problems are that the channel numbers don't move in the window, it needs a light for the UHF tuner, a brace inside neets to be reattached, and there's about 40 years worth of dust I have to vacuum out.
Once I get it cleaned up, I was thinking of messing with the height control to see what that does, if anything. It also looks like I'll need to straighten out the yoke, but it might be just my eyes.
Any ideas what to do next? Is the single-colorness going to be a problem? It actually looks like my Heathkit does, but then the blue gun kicks in and I get full color. Haven't had this set on long enough to see if there's any change once it gets good and warmed-up.
Forward!
