IC Video Input

I use a Signetics NE5539 video op amp. It drives the 1st video amp grid with at least 3vpp and also the video monitors I use for all PQ comparisons.

Thanks very much for the NE 5539 information and schematic. There are instances where as much as 8 volts pp are needed for some sets and also opposite polarity video at that same level, so I'll be breadboarding this to see how far I can push it.
Regards,
Cliff
