Accuphase A-48S

However, according to the brochure of C-2300, it is marked as 120V, 220V, 230V AC (voltage is shown on the rear panel).

I have checked the rear panel, but there's no such marking.

Would you please take a look at the following photos? I have marked one board. I was wondering if it is a board for standby/power-on function.

Thank you in advance.

Sorry, I can't clearly see and identify any components in the photo due to obstruction of wires. Can you post some clearer photos showing the auxiliary transformer? Is that power switch assembly board?

Thanks

Here are images for those boards:

Hopefully, you will be able to identify some components from above images.

Thank in advance.

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.

Thank you very much for your providing information on the transformer to be replaced. I will try to get it and replace.

I will let you know as soon as I complete to replace the transformer.

Thank you again.
