on luma in an s-video signal before mixing luma and chroma.
That would eliminate it.
Are you reffering to the "blooming" color lines in the convergence pathern? If so that prefilter should probably give me a sharper , more defined picture right? Also, as we are speaking filter, I wanted to ask about barberpoling effect and comb filter ; is there a way to minimise this effect on older television as if they would have a built in comb filter? I may be talking non sense here, but it seems that all my 1983 and plus televisions seems to cope way better with barberpolling than , lets say my 71 zenith and my 76 Quasar.

BTW the IF board on the Zenith is a 150-170, if anyone has one lying around and is willing to sell please feel free to PM me.

There is also one speaker I would need, its the one in front of the convergence board : 49D1194. Mine is completely destroyed (got to wonder how that happened :/ )

Thanks!
