As noted, Zenith transformers tend to run hotter than others. You may not necessarily make it run cold by reducing input voltage, only less warm. Subjective.
Having said that, you should use a voltmeter to see the affect of the 20 ohm resistor on input voltage.
The 150 ohm will reduce input voltage much too much. You can experiment with the 20 ohm value. But you need to measure voltage too and not just heat.
