What help you need? You must know what voltage and current your circuits will need and then to set the regs. The R1 for mA and trimmer for B+. Like in LV1.

Make the standard example, feed it 275V, set it 260V. Drop with RC for 220V first stage. 48k, 47uF.

966=967 without protective Zeners. If you don't normally mishandle, 966 is less components when P2P, easier.

I see no reason why it would not work. Report back if it will so people will know about that one too.
