There is a nice little 17VA transformer made by T.Giatras in Italy.

Their transformer IPOO CLF has a copper shielding to minimise magnetic effects with such things as RIAA amplifiers.
I have been quoted 12 Euros + VAT 24%, Post & Pack extra.
It has dual 115v primary windings and two separate secondary windings. One is 240V 10mA and the other is 14V 1 Amp
Although this model is not shown on their website, there is a nice little kit that shows the transformer in use:-
