Got it. Hamish you probably made a decent decision by combining Scott's DAC with the tube output.

I am changing my PCB of the '97 Kusonoki with that tube output. Not being an audio-engineer I can get away with that
Where's that dark voice saying it's not upon me to decide that...

Wow. Another nice hour of tweaking. I had 2x1K I/V and 1.2 K Vref resistor in my DAC. I changed the latter to 1 K and the sound improved again. More dynamics, better bass... yeah baby! And what a detail ! (listening now to a camp fire from a Solitude CD...)

I can't believe that I am listening to the same sound installation. Yesterday my set was tiring and had a lot of distortion and muddy bass. Now after two simple changes it rocks !

I use a 7806 now, I think I will try a 7805 too this weekend (and the 3.3 uF)...

Thanks JP!

JP, you mean that I should have a look at the software he mentions !?

BTW: did you compare 5V and 6V supply for the DAC ?
