Here is something my friend built recently, needs to be cased and PS will be separate. Ignore the fans, the heatsinks used are scrap and not up to the task. I will get my friend to post the schematic.
The amp sounds really good with the HD800, find myself listening to this amp a lot recently even though I have the DiyT2 and new dynahi on hand.
It is incredibly musical and engaging with the right tubes
We may bring it to the upcoming meet in southern CA.
