I went over there , and looked at it, The set was just out of adjustment on vertical,horizontal width, centering height, and the tube was also not centered on the platform behind the mask.
The sound problem was the channel selector, it seem like it was just "dirty", after switching channels about 10 times the sound was working much better.
We watched Charlies Angels from a DVD player for an hour.
The set is slightly unstable to power line fluctuations, and the contrast and brightness also affect the vertical and horizontal hold somewhat.
All in all it works pretty well.
A video of the cabinet restoration, the owner said this is his actual unit being restored.
