I realised my AD827 was not the same after i posted it, however I don't plan to be using an op amp in the future as I much prefer a discrete approach these days. I had great success with Giorgios (from TNT Audio) output stage on my TDA1541 DAC Just a matter of time before one of these is hanging off the end of this little gem.
My next project for this DAC will be Broskie's Unbalancer.
It's not too late at all. Post a pic of your trafo secondaries and one of the guys will help you.

There are no + & - wires coming from a transformer as transformers are AC.
Post a pic of your T/f and maybe we can help.

thanks for the reply..
i'm sorry, what i meant is the wires in the secondary output, there will be 4 wires. i was thinking maybe i can get center tapped by connecting the 2 middle wires?
this is my transformer: Buy Toroid Transformers Transformer,toroidal,30VA,0-230V pri,50/60Hz,2x0-15V sec Nuvotem 0030P1-2-015 online from RS for next day delivery.
by the way, does anyone have the schematic of the dac module?
i'm planning to use unbalancer for the output stage, but i have no idea which regulators and other components will be effected if i don't connect the 13-15V supply voltage (as far as i know, 9-12V supply voltage is for the dac section)

Based on the datasheet on that site, I think taking the yellow and black together will give you the 0 Vac point. Orange and Red are then the 15 Vac points.
Orange - Yellow/Black - Red

Just take a look at the first post...
yeah, thanks for the hint.. i got it later last night
i thought so.. thanks!
does anyone here compared the stock ak4393/6 module to cambridge audio dacmagic? how's the result?
i'm coming from dacmagic (which i like quite ok), so i wanna know how my dac performs. if at least the ak4393 is in the same level, i think this would be a good upgrade since this dac is a lot cheaper
i have tried my friend's ak4393, but his use broskie cathode follower in the analogue stage. i admit his DAC is MUCH better than my dacmagic, and in par with the elektor 2000 DAC. but please bear in mind, the analogue stage is BCF, not the stock opamp or any other opamp

Hi Bill,
don't worry about it, if you look at the schematic you'll find those pins are joint.
Thanks Dario - I saw the same bridges on my new board today and was suspicious. Glad to know the supplier is taking care of us.
See post #1077 for details of shorted pins.

no one?
Thanks
Phew! Thanks Dario, and jnewbold,
If anyone is unsure as I was, check out the schematic
and post #1077.
Time for some iron ing!
Cheers

i'm about to order the transformer for this dac module. i want a separate analogue and digital supply so 9-12V and 15-0-15V will be feed from different transformer
regarding the 9-12V trafo, 2x12V 0.25A should be much more than enough for supplying the digital supply of ak4396, right?
thanks in advance
