Direct video injection on a Predicta holiday

[tom.j.fla]

C20 is a good place to inject your signal. Be mindfull that the contrast control will not work in direct injection mode as it is a gain control for the I.F. and R.F. amps. Some other means would be needed to control the contrast in that mode. All the best,Tom.J from Fla

I'm not smart enough to snip the section of the schematic, but here is a link to the Sam's: http://www.earlytelevision.org/pdf/P...Sams-439-1.pdf

Uh oh. Any suggestions as to how to accomplish this? This is my first television and my ignorance is profound.

Thanks folks!
