Thanks
Contact Spencer who is a diyaudio member selling the D1 clone board here. He may have some CS8414 for sale.

It will be a while longer before I start building up my DAC-END2 as I have a few other projects that I need to finish. I have already bought and plan to use the Sowter 9762 transformers. I also have my own tube output board I'll be using with a CCS loaded 6H30p-DR. The tranformer will go directly after the 220R I/V, and the out put stage just after the transformer.

here's the link:

Hi Quanghao,

I received a set of pcbś from you last week and am pretty sure this was sent by mistake as one set was ordered. I sent an email to your mail account with details.

Cheers,
dshambala

I have 2 chip AD1864, so can I use it for this DAC. And I have 6DJ8, 12AX7, 12AT7, what is good for the I/V( for the best midrange).

with LED bias and CCS i am very pleased with the sound... its natural yet detailed.

CSS has been removed temporarily as i need to work out better heatsinking, or just put a big resistor with the B+ to drop it to 180v or thereabouts.

without the CSS i think it actually suits my fullrange speakers better, a little more warmth and less detail but it doesnt suit my 3way speakers as much (which to be honest arent that good speakers anyway).

the best improvement was the LED bias, it suprised me to be honest!

Congratulations!

You try to connect in parallel with the LED and a 1uF capacitor mkp or larger bit.

I will try for you.

one of the big positives of led bias is the removal of the bypass cap though. I dont think the small negative feedback produced is a bad thing either.
