Bose L1 Model ii, PS15 DSP PCB section A issue

Hi,

Do anyone here have schematic diagram for the DSP PCB section A?
I have problem with the 1S power stand. The power is not turn on and the -15VDC regulator is broken

Where can I buy this card?

Thanks for help!

Best regards
NamTr

No, and I have sent the question to Bose custom support. I hope that they have circuit diagram to DSP board.
