Hi Techs, This RCA part used in the PTK169 RCA projection sets is NLA. I have a customer that needs a focus/screen block for their PTK169. Tritronics lists some generic blocks, two as misc. vendors and one from Asti Magnetics. I have done some research at Repairworld and many techs say these generics are junk and don't last long. Anyone on this forum have any experience using these generics. If you have please let me know what vendor you used and if the block failed prematurely. I told the customer I would do the job but due to the circumstances I could not warrenty part or labor. Trying to cover my butt on this one! Ant info would be greatly appreciated. Mark Osburn J.M.
