The Nixer posted this comment on my Flickr page and I thought I'd share it here.
It's been years since I saw this movie and certainly didn't notice the Admiral at the time. Very cool to see one in action in a movie I think. Quote:

I recently pulled this set out for a little tuneup and thought I'd update this thread.
First off, that rubber to metal cement really did the trick. All four mounts are very securely attached now. http://farm6.static.flickr.com/5028/...74c49d84_z.jpg Next up, I removed the rust from the back, polished it up and clear coated it. http://farm5.static.flickr.com/4111/...763c2f2c_z.jpg http://farm5.static.flickr.com/4095/...ef6238bd_z.jpg Then, I polished up the faceplate with Novus 1 & 2. I also attached a new foam surround with a little contact cement. I used it sparingly and had no problems with it attacking the old plastic. http://farm5.static.flickr.com/4096/...1fb68d1b_z.jpg I also finally got around to cleaning up all the grillework. That grille cloth has really faded. It looks like the original color was green ? http://farm6.static.flickr.com/5145/...583f23a0_z.jpg http://farm6.static.flickr.com/5143/...37433710_z.jpg Here it is all back together.

While I had the chassis out, I also replaced most of the tubes in the tuner and IF and did a full alignment. It made a big difference in the picture quality.

The bands on the far right are 4.2 MHZ and just barely discernible. The B&K 1077B test pattern looks pretty good too :) http://farm6.static.flickr.com/5185/...a1f8622256.jpg http://farm6.static.flickr.com/5147/...8afbb09a16.jpg http://farm6.static.flickr.com/5187/...c3ebac92da.jpg There's just one problem. Now, I'm seeing what i believe are called 'chroma dots'. I recall reading a tip about using the green component output of a DVD player fed into an RF modulator. I tried that and it definitely did the trick. Does anyone know any other tricks to reduce or eliminate them ? http://farm6.static.flickr.com/5270/...e1e8cd4001.jpg |
If you have a DVD player that has component output, hook the Y line into the set right after the detector. You won't believe the difference!
Barring that (you don't get sound unless you hack the audio section as well), you'll need to filter out the 3.58 info to get rid of the dots. It's really bad on a Philco-Ford set I just got (which is color but still suffers), the dot crawl is atrocious. I don't think it properly filters out all the info for the chroma section, there's obviously still 3.58 in the luma. Some kind of tuned trap is what you'd need, good luck with that. I've been toying with the idea of feeding the Y and audio lines right into my Magnavox modulator, and feeding the TV with that on channel 3. Maybe you can do something similar? |

Too bad my DTV receivers only has RF and composite output. My cheapo Comcast box is even worse - it only has RF output. I generally use a Blonder Tongue agile modulator to broadcast to my sets and they only take composite video. I suppose I could try a 3.58 MHz notch filter like this: http://www.allenavionics.com/LC_F/NTSC.htm |
Watched all eight videos on the restoration of this set. I learned a lot but still don't feel ready to do a restoration yet. For the time being I'm just collecting as many interesting sets as I have room for.

Viry nice work, I wish I had half your ambition.
It looks like those chroma dots are not really visible from a normal viewing distance? That set now has an incredibly sharp picture. Maybe you've gone and done "too good" of an alignment. In other words you could mess it up a little. :D Kevin |

Si it should produce really good pictures on your set, it does on mine. |
