1970s Zenith Console - Troubleshooting

Update 4: I pulled the Horizontal Output transistor Q216 and measured collector to base and collector to emitter for a short. I did not find any.

I reinstalled Q216 and unsoldered the input from the flyback to the tripler. It is still tripping the breaker and there is no high voltage crackle.

According the schematic after Q216 there are multiple capacitor that could have failed and are shorting to ground. I will begin checking these.
