Tube Line Stage/Preamplifier
This is my 4th tube preamp project, but the first to use 12AU7 tubes and certainly not the last. Some of the parts used are from former projects that I made but don't use anymore. I hate wasting parts so why keep them sleeping? Build something new out of them! Of course, trafo and chokes are brand new. It uses a modified solid state power supply section and a DC regulated supply with slow turn-on for the heaters.
Here are some pics...

Almost finished...

Tubes installed, ready for testing!

I used my Leach Amp for testing this baby...



All in all, the sound is great, very satisfying. Some of my friends who heard this preamp are very impressed!
