Yes, that makes sense. The tuner is not an issue right now, since I have disconnected the video IF section (and upstream of that, the tuner) to inject a video signal directly at the 1st video amplifier.
When I had things connected normally, I could observe differences when using the fine tuner to tune on either side of the "best" signal, but the TV never displayed anything resembling correct colors. I have done this with various sources -- DVD player, agile modulator, pattern generator, etc. The AGC and color killer appear to be working normally, too.
