Thanks everyone for your help! I have finally completed the digital section of my DAC and I am currently coming to the tube output stage with the 3a5 design! I am still a bit confused with the circuit schematic.


I am going to use one tub for each channel , is this correct?

F1 is connected to Pin 1 and F 2 is connected to Pin 7, correct?

What about pin 4? Does it need to be grounded? Or is it connected to the R7 (150) in the schematic?


Thanks

Default SE tube buffer

A question:

I'm building cs43122 DAC recently.

If I use the 5687 version of output stage published in
http://www.ultranalog.com/cdenhancer/cdenhancer2.html

but with only a HALF configuration:

cs43122 AOUTL+ ( ignore AOUTL- !!) ==> 5687 ==> SE OPT .

Does this configuration still sound good?
