Edit: hope we are both reading the same schematic (rca_ctc16x_sams-0818-2.pdf).

Yep, Sams 818.
Measuring 25k across coupler C23. Need to lift a leg and get a real measurement on that little cap. The coils you mentioned are underneath the board. Hopefully they're not bad, as only a parts chassis could supply a replacement. L12 is after my injection point that didn't show smearing. So, yeah, L10, 11, C23 or a drifted R60...
