I also would be interested in seeing the model # of that Hoffman. The 1954 Hoffman 1954 15" set used conventional RCA type wide-band I/Q demodulation. Their next set, the 21" model, used conventional narrow-band R-Y/B-Y demodulation.

Thanks Steve,

Your answer is confirmed by the knob types and their placement on the CTC9 Models, with front controls, as shown at:

Thanks for solving the mystery. Now to find the model number.

Has anyone seen this set?

Have seen a few Mural CTC 9 sets but it has been many years ago. Correct about this being a custom installation chassis. I repaired a few of them in the past (one was installed in a custom Barzilay type cabinet with HH Scott Amplifier and tuner and a Miracord record changer. Speakers were Altec Coaxials.)
