Freimut,
I've got a spare (New) one that you can have for £20 (Which is what I
paid for it).
Any good ?

Do you mean the internal DC-DC converter, or the external PSU brick? The
DC-DC board is the same, but I've never seen a TA brick.

I've just dragged my TA out of the cupboard and attached it to an A4 PSU...
not a sausage. Now the TA has never worked so far as I've had it, but I
think I got more life out of it (maybe a few lights?) with a charged
battery. So I don't know for sure. Same connector though.
