That is just the shipping charge alone..... so one piece IR-1000 would be ~210USD.

I don't know, maybe that's still a good deal, especially if you buy more than one (even out the shipping charge).

I think I will go with some boards available locally though. I don't need 1000w @ 2R anyway.....

I don't know... it doesn't seem to be that good anymore for 210$
I have my amp7 for much less, and it is 2x 900w into 2R... so my point here is, for about 150$ I get much stronger amp right @ home and I say that is way cheaper... I don't pay for somethig from USA and back again 160$ for shipping, so why is here so much??

I would recommend buying in a good working pcb for the 2092.
The 2092 can be a nightmare with resetting, pcb layout, decoupling, gate driving, power supply etc.

well we don't have anything to go by, so... what doesn't work? what does work? what is the same and what is different with your amp from IRAUDAMP7S?

Did you copy exactly the iraudamp7 and pcb layout ?
The irs2092 is very fussy about pcb layout, decoupling and over current settings.
Are power supplies ok to the 2092 ?
Does it oscillate ?
Don't use it without a load as sometimes they can just sit with output at +17VDC ! or ring like mad and blow up output capacitor.

I made a post with the part of the scheme that I set up to see if it works and so far the post was not. I'll cuddle a little and see if the post will go.
