Hi,
Thank you for followimg thu’ with me…
Unfortunately,not. I had to leave London as I had to return to Australia and get back to work as my holiday in London had come to an end. So I left the sub with my son-in law.
I did not have the necessary tools to work safely so put the project on hold.
My son-in-law and my daughter will be visiting us in Australia at the end of the year, and I am hoping he brings the plate amp with him as I have the tools for the job.
The connector to the main board was heat damaged so unless a replacement is available it will be difficult to work on or test the board.
Any suggestions will be appreciated.
Kimd regards.

As seen in the first picture in post 1 the diode D1 may in fact be defective.
You can check this in circuit. It may be a zener diode.
Finally you should provide the correct name of this subwoofer to avoid frustration.

I doubt that A8H is a subwoofer. If the model is in current production, schematics will not be available.
Ok. I won’t argue.
This is the item I am sitting with on the workbench. (Refer to attachment).
The boards have Ice power and B&O markings on them.
Adam Audio, Germany technicians have confirmed it’s a Sub 8 and that schematics are not available. (which I am aware).
You obviously know something I don’t, as I am just a diy hobbyist trying to salvage what I think is a nice piece of audio equipment.
