Bob,
Outstanding restoration of the cabinet and chassis. The technical workarounds speak to your expertise in solving problems when original parts are no longer available. Great addition to the 15" family of color sets. My only, and minor, critique would be the dyeing of the grill cloth. See you at the ETF, -Steve D.

That is just beautiful color in that picture! I may have never seen better color on an NTSC display of any age.

What is that chalky substance that gets on (and, it seems to me, into) Motorola knobs, and how do you clear it out?
P.S.: stunningly beautiful work! |

As for cleaning the stuff off of the knobs: I use a stiff plastic bristle brush and also use my finger nails to scrape the thick layers of white stuff off. Then I polish the plastic with white automotive polishing compound and a terry cloth rag. After cleaned and polished and nice and clean, I then spray with the ACE clear gloss lacquer and force blow dry with a hair dryer. Test the spraying of the lacquer on some old knobs to perfect your technique before you spray the knobs you are restoring. You wouldnt want to botch the spraying of the lacquer by applying to much or not enough etc. FYI CAB plastic will melt in lacquer thinner, so this whole spraying procedure needs to be done to perfection and you can easily botch the job if you don't get it right the first time. So practice, practice, practice on old knobs before you risk doing this to the knobs you intend to restore. If you decide not to protect the knobs with clear lacquer, your knobs will continue to get that chalky residue again.. It is some sort of oxidation from the atmosphere and only clear coating with lacquer will inhibit the reformation of that stuff. Bob

typical Bob Restoration!
Somehow I missed this thread on your 15in Motorola untill now. I guess I was distracted by my 21CT55's demise. It ranks right in there along with your 21CT55. I knew you were working on one, glad it turned out soooo good! I was really impressed with your last color bar screen shot. The colors are so vivid and the red is the purest I’ve ever seen. Maybe all the hype about the original phosfers is true? Does your 21CT55 with the 21AXP22 have the same reds and greens, they must be side by side upstairs by now. I’d like to see the color bars on both sets using the same camera settings. That ought to prove if they used the same phosphers........Tom

Hi Tom,
Yes, both sets are side by side in the livingroom now. In a side by side comparison, I can tell the two sets are nto set up the same. Because of that issue it is hard to make a phosphor comparison. The Moto is leaning toward the green and the CT55 is leaning toward the red. I would tinker but my living room is very tiny and I have barely enough room to place the sets, let alone move them into a position to work on them. So I think for now at least, I am going to just let them as is. If I get time I will post a side by side photo of the two sets, with color bars adjusted to as identical as possible, so you can see the very aparent color mis-alignment. Bob

Comparisons
Quote:
Hmmm. Is the MOTO a narrowband R-Y, B-Y or a wideband I-Y, Q-Y like the 21CT55? Looking forward to the comparison photos. Shouldn't effect the saturated colors when judging the phosphers though? Tom Last edited by Tomcomm; 04-12-2010 at 09:18 AM. |

I can answer that: the Motorola uses narrowband demodulation.
What happened to your 21-CT-55 chassis? |
