This PCB look seem to same as Audio Note DAC 2.1x but I can't find I/V transformer so I used only I/V resistor instead of I/V transformer, from 4 PCBs of original I modified to 1 piece completed borad
In cluded :
1.Digital board (groud shield) cs8414 + ad1865n-k
2.Digital & analog supply board
3.Tube output board 6X4 RCA + 2 Pcs of 6922 Phillips JAN
4.High voltage regulated supply board (adjustable)
I have only 1 completed PCB of prototpye
I ask for 350 USD included power transformer but excluded chassis, included shipping
If include chassis plus 150 USD (2Kgs)
Paypal accept

NEW PCB
For special offer with a new PCB plate throgh hole 2 layers.
Hovland coupling capacitor, 6n23p output tube (very realism), extra low THD of pulse transformer, high speed MUR diode, good I/V audio filter choke
This board 100% worked fine & high quality sound when compare with other DAC or CD player lower 3,000$
You can adjust voltage & current by yourself !
I ask for last price 300USD !
