Your Sams doesn't include model waveforms for the vertical circuits, unfortunately.

It does include a voltage chart. You can use a voltmeter to check voltages on V13 and V14 and then compare them to the voltages given in the chart. If you find one that's way off, you can then check the components in that neighborhood. Put one hand in your pocket when touching the voltmeter probe to anything on the live chassis.

Also double-check your previous work, making sure that you (or a previous handyman) didn't miswire a replacement capacitor, drop a blob of solder somewhere, or accidentally nudge some component so that it creates a short circuit. Even experienced restorers slip up every once in a while.
