Ahh I see. But what is that small transformer for under the PSU? I'm assuming that is the blue box on the board, which I thought was a relay. That is a lot of extra work with the power supply! NICE! Sometimes the complication at the power supply side is necessary to get better and more stable volta...

So Frank, it seems like you have selected the circuit for the tube preamp. Is it just a question of finalizing the component values and tweaking it a bit. How much gain do you think you will need ?
