Having no knowledge of Indonesia I can only guess, so may be entirely wrong, so act accordingly.

It sounds as if you have a serious grounding condition – this could be dangerous, so I would strongly advise you to get this resolved.

The fact that using the H9 makes the louder noise is probably due to effects emphasizing some frequencies more than others.

Get a good electrician very soon !!
