Super V/i converted (LL1684 )

Super V/I converted For DAC

OUTPUT STAGE WITH LL1684 LUNDAL TRANSFORMER

After many listening tests with my friends I consider this configuration as the best.

The LL1684 with the amorphous core is the best choice as output transformer.
This is the circuit diagram V / I LL1684: Super V/I

Quanghao,

Can we buy the parts directly from you? ...or do we need to buy them from Parts ConneXion and K&K Audio?

 

[palmito]

r3/r4?

Hi Quanghao. R3/R4 on the image with the components listed appears to be smt, but the images of the board have it through the hole? Is going to be both? I have some through the hole I would like to use. Thanks

A very nice design and components chosen indeed...
BTW, I have order a discrete output stage for its headphone driving capability, so I would like to withdraw this order. Thanks.

Quanghao, is it possible to get this kit with all the parts included? If not I'll order them from the vendors you listed.
