Thank you for the photo. I googled the label "HPT 3512-5" on the transformer and found the Cleem Linear Transformer 1.5VA-3512 series. You will need to replace it with a transformer rated for 230V. There are a lot of uninstalled components on the board (716-0962-01) and I assume the circuit complies with EU regulations and powers down after a period of inactivity.
I think it would be best to order a 230V rated board (716-0962-07?) from the Acuphase factory to replace the 716-0962-01.
