Connected up a bridge rectifier to the mains input of the GEC BT5144.

The results are interesting. The upper waveform is the 100Hz voltage from the bridge rectifier. The lower waveform indicates that at 1amp the charging current is only slightly less than readings given in the previous experiment with the 50hz half cycles. (1.2amps) The discharge current is up to 0.3amp and the reason for that is because the HT voltage has risen from 220 volts to 252V.
Likewise the voltage across the reservoir capacitor has risen from the previous reading of 240 volts to 275V.
