I have an electrohome marquee 8000 that was retubed before I bought it. I'm extremely pleased with the performance through my Iscan PRO, but after doing some research, I found that there are mods to reduce the PJ noise, as well as create a true 16:9 ratio. What three resistors do I need to change to achieve this? How do I do the reduced noise mod? Is this mod recemmended, or will it hurt the PJ performance in the long run? Any help and information on this would be greatly appreciated. Thanks!
