What can I do with these transformers?

[keeeth]

Hi

I've got some transformers hanging about and I'm looking to do something with them.
I've got a load of Belclere TF10016 input transformers and some carnhill vt24499 output transformers.

Can these be used for mic pres? If so, does anyone know of a design I could build with them?

Cheers

Did you work something out in the end ?
