the ring is still there, slight but still there (its a ring not a ghost as you can see multiple diminishing rings. Its tunable so I am pretty sure its in the IF. It looks like this set relies on pressure grounding of the pcb's (not the solder stakes like later RCA color chassis). Any one with some tips on what I may look for as far as IF ringing (of if there is another area that could cause ringing? its in both the luma and chroma. I don't think it would be delay line issue since it is tunable.
