You might try taking your CRT to a television repair shop and asking to have the CRT "rejuvenated". There is a piece of equipment they may have which will bring back the brightness on your CRT for quite some time. My experience has been one to two years added life the first time the process is used. Additional applications are less successfully. Here is a link to the equipment used for this process on ebay. I have this same piece of equipment and have done hundreds of CRTs with it. http://cgi.ebay.com/Beltron-System-Picture-Tube-Restorer_W0QQitemZ290149557… There is another type of equipment which is made for the same thing which works by sending a spark (high voltage discharge) between the elements in the CRT, I have destroyed picture tubes with that type of equipment. Good luck! Les
