Ah right - so it's a question of wire thickness. So at 250v the current rating would be half of 50mA, so 25mA? That would change things. Is tthat the convention - if there's a centre tap it's assumed you will use it for a full wave bridge?
So in that case a hybrid bridge with choke input would give 225v at 23mA. If that's correct, that's not impossible for an 01A preamp.
The transformer is a very old RS one - Midget Mains. UK sourced.
