    This forum will not support the discussion of dangerous and unsafe circuits. Use a transformer and quit encouraging those who do not understand the dangers to engage in this foolishness.

    Remove FR, R1, C1, ZD1 and ZD2.

    Insert a 230VAC to 16VAC step-down transformer.

    That is the only way to make that circuit safe.

    Transformers are a remarkable bargain compared to the cost of a funeral.

    As has been pointed out the premise of this design is unsafe. It would inappropriate to allow this discussion to continue IAW item 2 of the forum rules:
