Hmmmm....looks very interesting. I see several other such models by different folks on 
eBay.

Has anyone tried these yet?

I've bought some of these and two other types, a 180v and 480v max output types. I have the one above powering my ARB set to 240v dc and it runs cold but it will need putting in a screened box etc before fitting in place of the dyno. 

The 480v unit gives 96ma into 5k so should drive a tx even.
