It's a tube used in Bang & Olufsen Beovision 1 consumer TV. It has no convergence rings and 6 pin yoke.

That looks pretty typical. It can't currently drive the rotation coil so you won't have rotation adjustment.

The neck board transistors look surprisingly small. Is a service manual available?

Oh, so this 2 wires aren't required to drive the yoke, just are responsible for rotation? I don't have any schematic, just manual which is'n very helpful. I could make some more photos of the transistors.

Update: I've opened today another Beovision1, an older SW 1.2 version and it has only 4 wires connected to the deflection coils. Red and Brown are NC.
