I only noticed 2 reviews that stated it had speaker or "cab" outs.
One guy, I think, mentioned he thought the amp could drive a cabinet.
Note that one review says the amp has no distortion. It has "Volume," "Gain" and "Master Volume" controls. It was made to produce distortion at low volumes.
It's just not a good idea to base your expectations on Harmony Central reviews.
The best photos you have (the ebay ad in French) don't show the speaker jacks, yours doesn't have them.
That's all you need to know.
Plug it in and play it 'til the manual arrives. When it does, you might not care anymore.
