The manual quotes a leakage test voltage of 175 volts, that will be the HT voltage.
No need to think about a bridge rectifier/zener etc, half wave will be ok.
I've no idea what the actual value of capacitor "B", the range, but it's in circuit on the divide by one hundred range so far as I can make out, so I imagine it will be a low value, possibly in the picofarad range.
If the 1uF capacitor is an electrolytic then +ve to HT +ve and -ve to HT-ve, If it's not an electrolytic it doesn't matter which way round it's connected.
