After completing my last project, ( https://www.diyaudio.com/forums/digital-line-level/291645-building-soekris-dam1121-post5511258.html and https://www.diyaudio.com/forums/digital-line-level/291645-building-soekris-dam1121-post5573707.html ) with great help from many of you in this community, I’m starting with a scratch and a design by Broskie.

I want a simple design, without a big part list.

This is Broskies simple balanced phono preamp:

That can be found here:
Still More Phono Preamps


My simplistic mind brought to me that it would be just perfect, to use a 1:10 step up as Input transformer 12ax7 as gain tubes, ecc81 as cathode follower and as an output transformer a transformer voltage control, (by sowter with +6 and +12db tab) wich will give up to 1.225V wich is just what my power amp needs.

What do you think?
