Hello,

I have found a jukka tolonen 6SN7 tube output stage for PCM56 DAC on triode dick site (http://members.home.nl/triode.dick/dacuitgang.html).
I have a pcm56 DAC and want to put this output stage in it.
On the schematic the supply voltage is 300V.
Does somebody can help me and give me a good and simple (whitout chokes) PSU schematic for this 300V B+ ?

Thank you very much to all.

Pascal.
