The 6GH8A madness continues...while sweep problem is all but gone, but what remains appears to be weak sync AND video, likely AGC.
So far it's crummy-looking video but chroma-locked color bars are good to see, the AGC control has no effect using the Sencore VA-48 at both antenna & tuner link going to first IF amp.
Unlike the 4-board color chassis like CTC-21/25/28..., the 2-pcb CTC19/20/24/31 video is taken off before a 6GH8 pentode section amplifies chroma/sync and AGC.
This is the last place to look before I move on to the CTC16X. I'm getting bored for now and need a change, that's why I line up triage of at least two similar sets.
