There is two different versions of the Zenith 11-S-474. One has ten tubes and the other has eleven tubes. I have two of the ten tube chassis.
The only difference between the two is the first audio and detector circuit.
The eleven tube job has a 6J5 and a 6F5 and the ten tube uses a 6Q7 for both functions.
