Most of the Zenith power transformer failures of the era were caused by the infamous 6X5 rectifier tubes shorting. No radio transformer was meant to take having its high voltage secondary shorted (which the 6X5s often did when they failed).
I completely agree with the rest of your advice.
Do NOT power it up with the rectifier tube installed until you are confident that you've found and fixed the problem...If there is any rubber wiring remaining in the set I strongly suggest replacing it...You never know when/where/how it will short, and if you want to use the set regularly the rubber should go as preventative maintenance.
