After purchasing this machine on Ebay I have decided to go ahead and haul it over to VDC at the Cape and let them retube it with factory origionals. The Panansonic tubes have 14,000 hrs with only faint burn marks but the light output is way down, more in the range of my old 900A. HD has never looked so good. it is incredible the amount of detail these old tubes have over the 7" Runco. I have had a 9500 with brand new rebuilt tubes next to the Ebay 9500 and just don't like what I see on the new rebuilts. Going to have them put in another RGB imput while there. Should be done by Thursday so will know over the weekend if this expensive trip was worth it. The guys at VDC told me that the rebuilt tubes would never be as sharp as origionals and from what I have seen I think this is probably true. Redoing my theater room has been a challenge what with changing scanners twice, Mike Parker mods, and other little goodies.
