Default IRS2092S Mono Class D board

Has anyone bought this particular board and had problems with it. There are multiple sellers of the same board but I bought mine from the link below. It powers on, but there is no output.

IRS2092S 500W Mono Channel Digital Amplifier Class D HIFI Power Amp Board Q D4B6 191466622261 | eBay

500W RMS Hi Fi amplifier for less than £12.00 ... not very likely to be 100% at that price.
I would put it down to experience, get the money back through PayPal and find one that works.
There are some very nice Ice Power amplifiers but make sure they are made by Bang & Olufsen, not the cheapo Chinese unreliable ones that flood fleabay.

Hi Jon, that was my thoughts. I have had other IRS2092 that have been fine.

I have read it. I can't find any reference to anyone receiving a dead amp.

What are the supply voltages applied to the board?
Both boards are the same?
The different versions with different power capabilities require different supply voltages.

I was looking at that this night to. I found this other one up to 2000W. Of course I donít believe it.
This was its title heading on fleabay

1PC IRAUD2000 IRS2092S IRFB4227 2000W Class D Digital Power amplifier board AMP

My sole purpose is to use it as a dedicated sub AMP.

I was not interested in whether the amp would give 500w or not as I wanted something in the region of 100w and for the price it seemed a good deal. I am now going to build my own board.
