I think Zenith used those demods till they replaced them with SS components.

Zenith may have had to buy those parts, but RCA had to pay Zenith for their little old inventions of Electromagnetic convergence and FM MPX stereo so I imagine it was a case of 'you begrudgingly scratch my back and I'll begrudgingly scratch yours'.
