Hi Colin,
Just a small point. Am I the only one having difficulty reading the very small font you use? Either that or my glasses prescription needs changing!

Now, where did I leave my white stick......

Ned,

Publish whatever you can read on your Tx. Richard has already published a link to the manufacturer on the forum although it would be good for him to raise it here. What you can read will allow Colin to order a replacement.

Best wishes,

Greg

I may be wrong,but I think I remember Mark mentioning Danbury Electronics,a small company local to WAD's sales centre in Essex,who not only have a range of transformers,but will also do custom work.

http://www.danburyelectronics.co.uk/
http://www.livinginthepast.demon.co.uk/valveaudio.html

These may not be the suppliers of the transformer in question,but may be of use in any case.
