This item and seller
IRS2092S 500W Mono Channel Digital Amplifier Class D HIFI Power Amp Board + FAN 809619936065 | eBay
Fans are still working.What is wrong with them?

One channel working.I will test other channel tomorrow.I shorted input and someone suggested not to start it before connecting to speakers

I made my Double Mono (IRS2092S) based on discret comp. boards
They sound particulary well. Nichicon Audio grade + Epcos caps.
Soundstage is really impressive
