A New Take on the Classic Pass Labs D1 with an ESS Dac

[gebi]

Somebody knows the size of the "D1" PCB and the total height with the buffalo DAC ?
I'm looking forward to buy the right case for it.

thanks

Hi Owen,
I just came across this thread, I hope not too late. I am very interested in a set (PCB + SMD). Please consider me in the waiting list. I will make the payment as soon as confirmed.
Regards,
Michael

Yea, I'm just crossing my fingers there is a second GB for these boards.

Well I ordered two sets, because a lot of ppl were dropping out and I thought that I might have use for it later on.
That later on would definately be a lot of time from now, since I have a lot of work to do with my current projects.

So I could offer you one pcb and one smd-set, but you'll have to take a set of fets, too.

Did any one try/ or know the difference between FQA34N20 vs FQA32N20?
TC should be the same but fewer Crss... Maybe a good choice.
I just got some FQA32N20 on hand.

Please advice.

THKL you have a message. Thank you

looks like you just missed another one :| if you ar4e dead keen and prepared to go to the trouble, I suppose its possible that you could get a batch PCB with opc's permission and help. they are pretty cheap these days for one off boards, well you would probably end up with 2 or 3. wouldnt be as high quality as ours, but should do the job. totally hinges on opc though and your willingness to go above and beyond

that being said, knowing how good this design sounds with the sabre, after feedback and impressions of this PCB come in, I would not be surprized if there was another run

Iloveswan: no sorry mate, dont have any experience with those fets. I think you'll probably find the difference is in the current rating, the FQA34N20 is rated for 34A and the FQA32N20 is rated for 32A. so are you saying you have some FQA34N20 on hand or FQA32N20? because the FQA32N20 is the one specified in the BOM, so you are good to go if thats what you have. either will do great.

depends on the standoffs and heatsinks you use (or if you use the case for the sink), also the main supply caps, these are the tallest things on the board, so work that out and you have your height, because the dac will not be taller than the surrounding components

I also would be in for a board. Completely miss this thread. Any chance ?

Thanks,
