But if i connect it to Behringer DCX2496 it works and i have very high output.
The input sliders at almost zero.
So its very high output from the player,but i cant tame it and get rid of the crackles that
come one second and disappear next and come back.
Any suggestions?
I experienced similar symptoms when my ground connection for the digital output came unconnected. check your ground.

Thanks for the tip okapi but, it sounds very good true my DCX2496 so i dont think i have any grounding problem.But it accept the professional AES also.

Is it so sensitive to the resistors that i havent found right value yet?

1. for PS. can i use elna silmicII (and or) nichicon KZ instead of BG? will BG be better?
2. remove R5 and E5 and choke. Or remove R1-R5, E5 and choke. is this also ok or leave R1-R4?

Is C952 the R5 and C916 the E5 on the pdf? if not what is it? where are the ceramic bypasses of C952 and C916 in the pdf?
BG will be probably better, but if you can't find them, use whatever else that works. Silmics have good opinion and are certainly worth a try.

To summarize my most recent mods, this is what I do:

I remove the choke and caps C916, C952

I still use external supply as posted on a first page of this thread. Two wires from PS are connected to the pads where choke was.

I add two output resistors: 300/100 Dale (when building for myself, I use Vishay S102/Caddock) and in place of C916 I instal BG N, either 47/50 or 33/16 depending on availability.

That's all the mods I do presently, for more info see this link: Finally, an affordable CD Transport: the Shigaclone story

I removed bypass C917.

Is the other one this circled thing marked JW927 ?

I cannot find a C963 as per the circuit diagram.


I replaced C916 with an ELNA 47/22 which iw the closest I have.

No, I think C963 is the cap down and to the left of that JW927 - just at teh end of the big chip HWCAT...... see, if you look closely at your photo you can actually see C963 written on the silkscreen beside it....
