Don't do it! You'll run the risk of taking out the rectifier tube, the input filter cap, and or the power trans. Without the speaker connected there is no load on the HV side of the power supply. This will cause the input filter to charge up beyond it's voltage rating. This in turn will cause it to short. Next goes the tube then the trans.
