Making a 6SN7 Tube Linestage // DIY Tube Stereo Preamp // New all Tube Shop Stereo System build!

Scratch build a 6SN7 Tube Stereo Preamp. I spend a lot of time in my shop and I figure I may as well have a great sounding stereo system!

The circuit shown is a mixture of topologies that I have build over the years. It is not unique and few will notice similarities between various circuits posted in tube literature and various DIY Forum/Communities. I do not assume any ownership of this circuit. This is posted for hobby use only. Feel free to copy, adjust and modify.
