Yeh, but ONLY with a converter (unless you get service from Translator,
or Cable) On the air NTSC ceases around middle of feburary! Brenda Ann wrote: "Jim-NN7K" . wrote in message ...

You can still use a converter box on your old RCA 630-ts. |

Thanks much Brenda. Your answer was very professional. Just like a tech would answer. ** Posted from http://www.teranews.com ** |

Just like a tech would answer. Where should she send the bill? I would qualify the above with the word "vintage" in your sales brochure. http://cgi.ebay.ca/VINTAGE-RCA-TELEV... QcmdZViewItem RF and IF alignments and mechanical tuners were rendered obsolete by monolithic filters and synthesized tuning. Convergence alignments are the last true skill of the purist, but largely neglected by manufacturers as few consumers are purists. |

Says first sold 1951 for $243 long before color TV and LSI. Oddly, they were often found in schools well into the 80s to teach the basics of the trade, even though current technology was way beyond (how do you calibrate with something less stable and accurate than the UUT). Generator with gun control? I don't believe in Gun Control. You would have to put razor wire all around the US, declare all the civilians "incompetent criminals" in order to abide with the Constitution, and even then the really BAD people would still have guns till the end of time, if only for infotainment purposes and shock value. There would be a rise in wild and stray protected animals killing hikers and pedestrians. But we digress. I went to a FM/AM service monitor. Performs all the functions required, but with stability and accuracy well beyond. Also combines several other test capabilities such as scope, spectrum analyzer and signal level display, although conversion from dbm is required. Convergence alignments are made more or less simple by the CRT technology. RCA XL100 was a great line. I did Zenith (Works in drawer until you slide it back into place, Quality goes out before the name goes on). After that, Cheap was the name of the game. Sylvania, and others were difficult to achieve convergence (to my standard) due to oversimplification. Gun controls were removed except for drive and bias, and the alignments were left to the tube manufacturer and mechanical ring magnets. Shipping would often goof up your good work. I would go through showroom after showroom of various makes and models and be completely disappointed and wind up buying from Kmart and set about to fine tuning the purity and convergence. Now we have all the HD big screen technology, but all the potential customers are trained for disposability by $8/hr pimple faced floor sales people. |
