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.
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

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

Default Sloppy or intentional?

Hi Folks,
I was about to send this board back but I though to check the schematic and it looks like the shorted pins on the two IC may be intentional?
Can someone please confirm this is not just sloppy solder work?

Thanks
Bill

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.

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
