Hi Barry
The transformer came pre-soldered that way. I wasn't using a light bulb tester back then so I'm not sure if would have protested. Unfortunately the solder pads were so far gone the dac eventually packed up. I have considered getting another but I've been dabbling with various projects since and its always been put on the back burner.
I see you have been working on some new CD enclosure designs, looking good as ever!

hi everybody,
this is my first post here and sorry for my bad english.
i have some problem with the lampucera DAC.
the optical toslink work fine but the coax seems dead.
no music but only rustling.:(
there is also a strong lowering of the light of the red led.
maybe the lampucera has passed in R.I.P.(Requiescat in pace = Rest in Peace)?
thanks for your help.
R.I.P. = Rust In Pieces
:lol:
Hi Roberta, the RCA fitted for the input spdif on these dacs are extremely poor, I had problems with the ones I was modding, yours may be ok but I'd try replacing it just incase
The ones I modded did not have any led, I presume the led is the locking indicator for the CS8416
thanks for the very fast reply.
i have modified the lampucera following the fikus project.
i have never used the coax imput until 5 or 6 day ago because my cd player was unprovided of the digital output and the lampucera was connected by optical to my MacPro.
now i have the cd player with the coax out and the lampucera don't work:steam:.
thanks for suggest and i try to change the input connector.
very interesting the removal of output elko replaced with the film condensator close the output connectors.
p.s. for Leo: my name is roberto.
Hi everyone!
Anybody tried one cs4397 per chanel?
With two chinese cs4397 boards is it possible?
Thanks
Need some basic help. First let me state that my background is in mechanical engineering rather than electrical but I do like a challenge.
So far I’m using this dac stock with the supplied power supply. I was happy that it worked at all after I hooked it up. First problem I noticed was it is louder in one channel and I have to use the balance control on my preamp (lucky I even have one). So I have been looking here for a solution.
Could the different values of R8, 9, 14 & 17 cause this?
Later on I read about that someone had a bad voltage regulator, I figured that is easy to check so I did and the +5 volts is +5.1v the +12v is +11.81 but the -12v is -16.44v. Looks like a problem on the -12v to me but is it causing the channel imbalance? I measured at the first power supply connector relative to the AG pin.
Regards.
Hi Alan ;)
What are you using the DAC for Computer?
