Ask Jan First ; electron tubes and more
go to 'output transformers' and look for STH20.

No idea how good they are...

Question Need more volumn Passive Pre with 1/10 transformer.

Has anyone tried using a passive Pre in conjunction with a 1/10 step-up transformer. What would the pitfalls be with such a configuration
