Hi,

Interesting stuff.

What advantages have you found with using the Sowter input transformer?

Does the transformer give you much extra gain?

Also, which model is the transformer (or ratio).

Thanks.
 
the ratio is 1:1 , so no extra gain. its a sowter 3603.
it´s more silent with the transformer, as the input stage is fully balanced now. (not by more-or-less matched input transistors any more)
