Mine is not done that way, no output transformer. The volume control is the one used for the stereo so they cant pick it off from there. maybe the older sets are that way without the stereo. All the parts to drive a speaker are not there on this chassis(C43).
As far as the chassis is concerned, it is RCA. All the same tubes and components. It's just modified in the audio output and power on/off controls. Flyback failures in this set are no more common than RCA sets.
