  MC phono stage without transformer?
A newbie question:

I read a lot of 'reservation' about using an external MC step up transformer to increase the gain of an MM phono stage. But as I searched around for MC phono stages, I noticed that a lot of these actually have internal step-up transformers, some of these transformers are exactly the same as what some people used to make their external step-up.

So if transformer is no good, I should really be looking for an MC phono without the tranformer? Do these exist though?

Palasr,

The Slagle autoformers are being used for the TVC.

A post from John on his Audio Circle forum regarding the step-up transformers:

"Finally I have a new transformer I am happy with. It's a unit wound by Magnequest that we worked on together over a good part of the past year. We tried quite a few options and this one really stood out from the rest and it felt good to land on something like that! Just now getting the shielding can's on order and arranging a production run with Magnequest so it'll be the end of June or so before I get the stuff needed to make the first production run.

Pricing should be the same as before - or very close. The 1:10 / 1:20 gain switch will be standard now."

He had a couple at VSAC so he is probably very close to full production.
