two kemper powerhead with dead leds............

Those with defect LED's should check with support regardless of estimated warranty status.

This. Also, not sure why an ebay purchase should deny a warranty per se?

I thought because not sure how old is the unit (but older then three years anyway), no bill or something like... German bureaucracy made me think that way. But it should be worth a try if I understood right...

Well, kemper are known for their willingness to help the most faithful users. Actually, the official warranty expires in three years, yes.
Anyway, they are able to go back to the pur hase date by the serial number.
I'd contact them anyway, there could be many ways to help you.

I ... German bureaucracy ...

What are you talking about?
???
In all seriousness, Kemper are everything but beaurocratic.

Wasn`t talking bout Kemper..., was about my experiences with warranty-rules and red tapes(?) in Germany, what affected my thinking...
