Hello,

Got several brand new TA0105A to make this awesome amplifier board:

Tripath TA0105A 800Wx2 Super Class-T Audio Amplifier - Boards | Kits | Components | Modules | Tools

No need to speak any more about this chip.

Also got several Icepower 125ASX2:
B&O ICEpower 125ASX2 Audio Amplifier Module - Boards | Kits | Components | Modules | Tools

Both boards has only a few pcs (each about 10).

Hi,
I bought a couple of these boards last year via ebay. I am supplying the following voltages:

SMPS.........TA0105A
---------------------
+80V..........+V
HV GND.......GND
-80V..........-V
AUX +12V...+12V
AUX GND (NC)
AUX -12V...-12V

+-5V PSU... TA0105A
---------------------
+5V..........+5V
GND..........-5V
-5V (NC)

The red LED comes on, but there is no sound (and no smell of burning silicon which is a good thing!)

Any ideas or know where I can get support from?!

Thanks,
Gareth
