Look for the ringing. Then simply remove the horizontal output tube and see what
happens to the waveforms. Make sketches of the waveforms and report back. Use
the grid of the horizontal output tube for sync of the scope.
If its an AC-DC set you can't pull the horizontal output tube ... in that case,
disconnect the plate cap lead.
That's the first step.

This is a SS chassis. I did all the waveforms and they, to the best of my scope's ability, resembled the forms in the SM. The scope was designed in the 50s and was meant for TVs, still I don't think it's up to the job. I'm going to keep an eye out on ebay for a used scope.
