Yes, thank you, it was in my bucket list. I've got the tubes and all the good parts collected. Do you also provide the PCB for this project? I was just about to design the PCB.

I have some my friends interested to build this easy and good phono preamplifier so if we will arrive to 50 persons the price should be only 50$ each including shipping cost.

This project use D3a easy to find on Ebay germany shop at 10-12$ each.

The sound depend by the passive components used.

I'm interesting :-)

I am interested.. Put me down for 1 set.

I am thinking to use a Salas shunt on high voltage power supply as alternative to the Virtual Battery.

This is a must. I wouldn't use anything else in low level circuits and power amp driving sections. In comparison series regulators really suck.

I am interested as well, is 50USD for the PCB?

The 50$ should include the pcb of the preampl., the pcb of the power supply and the shipping cost.
