Ok I just checked mine, the CTC-7 tuner is a bit different than the one in the video(video has tunable slugs for each channel, ctc-7 has a VC that effects tuning on all channels), so its possible that you may not lose sync (mine did but just barely).
but it was def fully CW for loss of sync and CCW I would lose color sync (rolling bars) on my CTC-7.
triple check what channel you are on and what channel the output is, but IMHO you need to be on the channel that has fully CW for loss of sync/dark pic.
You may have a problem with a converter tube in the tuner, OR your AGC may need to be adjusted.
confirm the channel and fine tuning operation 1st
then try a different converter tube in the tuner to see if that makes an difference.
lastly will adj the AGC, I did not want to go there since the CTC-7 has a different approach to that than later models, but its not a big deal and you can aways reset to the orig starting point.
