Almost done with my PSU. Just need to order some more caps.

I haven't touched the high voltage 150+ v for the tube stage. What have you done with your high voltage section? I'd like to figure out what I need for this and maybe stick it in with the low voltage stuff.

If I can get a hold of your drawings for the case that would be great too.

See pic - note that one of the pairs is D+/D-, the other is a doubled-up Gnd lead; there's no need for V+ with the WaveIO. (I didn't bother with a screen as the lead is so short. That, of course, minimises capacitance but I did it that way because, essentially, I'm lazy.)
Nice!

Where did you get the connectors?

If possible, even shorter is even better.

Because i use a SSHV per channel and a tube rectifier for the B+, you dont see a populated HV section on my photos

Witch drawings did you like to have?

I'd like to get your case diagrams. Hopefully everything will fit... and how you wired that connector up (that would be handy).

I might just be using an unregulated PSU for my tube stage.

I got a nice 17" x 11" hammond walnut case. Not sure if I should use it for the dac or the PSU.

How big is that case for your power supply?

Hello Oliver ,

maybe is something stupid i can`t figure at the moment but i need your help
I have connected all wires but nothing came , as far as I can touch every voltage is OK . Kind of wired but even 5 V is around 4,53 V .

My first suggestions are i/v outputs because i really hate to deal with them , can you please specify how to check output voltage ?

Another thing it seems that AOL and AOR differ ? one is 0.55 V other is around -7 v ?

Hi,

atm i am in holiday, so it's a bit complicated to say.

Did you do the MOS-Fet mod. for the V3.0?
