The spec is on the Harbach/Dahl website Dave. You can probably save a few by
having it rewound. If its no longer there I can dig up a hard copy catalog out
of the dungeon

courier's fees to carry out import etc it'll have cost me close on
GBP450. Our thieving government will charge about 6 percent "duty"
plus 15 percent "VAT" on the cost of the whole shipment including the
shipping charge.

expect to pay GBP200 or so, for a good custom wound transformer to the right
spec....if I can get hold of the spec!
