This is an unusual model in that it has the newer motorized veractor tuner like in the later vertical chassis sets, but still uses the older horizontal chassis. It's even called a chromacolor II, which I thought referred specifically to the vertical chassis, but it seems Zenith started using cc2 in 74 for both kinds of sets.

Whatever is wrong with the sound does not affect the picture at all, and changing the channel or adjusting the tuning has no effect on the sound when it goes out at all, so I'm fairly certain the problem is limited to that sound module. I watched it for several hours today, about once an hour the sound would cut off, turning the set off and on again always brings it back (sometimes I have to do it 2 or 3 times)
