silvertone contrast
 
hey all, is there anyone that knows how to increase the contrast to make the picture alittle sharper? maybe add a resistor to the contrast pot or some minor add on or change without trying to get more from the AGC.:scratch2:

what's it use for video output? you can add a simple dc-resto circuit with a couple a diodes on the brightness wiper. have a schemat-i for that someplace.
otherwise, make sure the video output and if stages are up to snuff..with proper greyscale and drive amounts.
