Well, you need to get rid of transformers and to make your phonocorrector to have no noise of any kind with any transformers. From MM level you need to have no more then 1-3mV AC at output and absolute not noise. After you do it, then you can add transformers to start to play with it.


It wants to be shielded. I've lined the inside of the signal steel/alu case with a copper foil (for furtherreference 0.3mm foil is way
too thich and hard to work with), closed the case and the ham is gone, my phono is vegetarian again!
No minor changes in layout could kill the ham with case open---the pickup from the PS was too strong
(my cabel is very short, 60cm of f...cking stiff cardas twisted pair f...ck! I'll double it soon). This makes me think to line the
inside of the PS case with the foil too so that it does not vomit the garbage all over tha place...

Now the fun begins with connecting the transformers...let's see...

Cheers,
