Phil, I'm also fighting a chroma-AFC problem in a friend's CT-100. It exhibits a similar off-color operation. In my case the oscillator is functional and the CW to the demodulators is there and at the proper amplitude. And, as well as can be seen on a scope, the CW is in quadrature at the demodulators.

As has been suggested here with your problem, I will next concentrate on insuring the Reactance inductor and circuit are working properly.

Closed loops are tough cookies to crack at times!
