As to peaking coils: don't try to find NOS ones. Just get the small to medium
size (size of old fashioned 1/2 or 1 watt carbon resistors) cylinderical axial
ones from Bourns or API Delavan. Get shielded if they have them. Make sure
the self resonance frequency is high enough.
I do very strongly recommend that you don't use the approx 6 mH specced
for the Q channel ... it seriously ruins the chroma reaponse. Get one that's in the 2.7 or 3.3 mH range.
They don't look right but work very well. You may need to search both Mouser and Digikey to find all values.
The picture on my CT-100 is the best recommendation for these.
The coil's Q is not a problem, all of those coils are plenty good enough because they
have ferrite forms. The shielded ones also have ferrite outer shields.
