Direct video injection on a Predicta holiday

[madlabs]

Hi All,

So, I want to try direct video injection on my Predicta Holiday, primarily because I want to see how off my IF is. And if it looks way better then I'll probably feed it a signal that way. I'd prefer to receive the signal through the antenna as intended, but I don't have the tools or know how to align the IF. This being a hot chassis set I know this is a little riskier than on many sets but if I always run the set off an isolation transformer I'm hoping I'll be ok. I picked up a $15 DVD player with composite output at the thrift store, so if it explodes in flames I won't cry.

So, looking at the information at Phil's site, it looks to me that I would inject the signal right after C20 on my set. Is it possible to inject the signal just before C20? I ask because that would make the connection point very easy to access. Also, should the output from the IF be disconnected before attempting to inject the signal? Any other things I should look out for or know?

Thanks!
