Thanks again
Snowman_al suggested 120VA, which is better than 50VA. Transformer prices don’t vary so much at that rating, and size should not be an issue. Your favourite auction site can be an option.
Thanks Richard
Its seems they do tend to go up a bit, i'd like to keep it small as much as possible to keep its physical size down so i can make it fit in on the chassis as much as possible.
