FS:D/A AD1865N-K Non Over Sampling
 
I used schematic from AN DAC KIT 1.1 but I modified solid state high volt rectifier to tube EZ-80 rectifier and used walt jung super regulator + spectral dms-20 instead of original supply.

All parts applied on single PCB (receiver + DAC + IV + tube + all supply)

I sale only full assembled PCB + transformer.
I ask for 315 USD shipping included.

My board included cs8414cs, ad1865n-k, ecc82, ez80, all digital and analog power supply.

I have only 2 set of PCBs

Thanks

I used Nichicon FW for 5V digital and +/- 5V analog supply also filaments rectifier, 0.47uF/400V spargue orange drop for tube output.

For analog filter I/V used RLC circuit, 1% resistor + 12mH separated coil + silver mica 0.01uF

EZ-80 for rectifer with PI stage filter which used 1K and 2.2 K resistors and rubycon 47uF/400V for filter capacitor.

For cathode bypass I used 330 ohms parallel with 220uF/25V phillips axial leed.

This's my hobby.

Thanks

This's a schematic of my DAC.

I learned from many thread of AD1865N-K from DiyAudio, now I worked on SMPS design department but I loved DIY and sometime I used a freetime for design about digital schematic such as DAC, Class-T, Wireless LAN.

Thanks for contact
