HELLO; I have a ram x070 replacement for my 51 zenith chassis that uses a s-17233 fly, and want to know if anyone out there has ever used the x070 replacement, ( this fly also replaces s-17130-s-17140- and s-17265). having trouble with the wiring hook-up ???. Could some one give me the correct terminal connections for the application???. I have had past problems with the old fly, when I advance the horiz drive to get the correct width and brightness on screen , the 5u4 starts to glow. thanks chip
