I was wondering if anyone knows anything about these transformers, as Google isn't showing anything useful.

I recently bought a small (likely home brewed) box with a Mckenzie F800 transformer. It's supposedly summing 2 inputs to 1 output, I've bought it to sum the outputs of my 4 track to mono, and it's working and sounding fine, although, admittedly I've no idea if it sounds any different than just going out of the 4 track with either of the outputs, haven't really done any serious testing yet. But it does sound OK.

Visually, I had never seen anything like this, as the transformer looks "hollowed out".
No idea of impedances or anything, really, other than the fact it sums 2 outputs to 1.
It's also quite light, much lighter than any transformer coupled small thingy I own or owned before.
