AudioNote Dac Kit 1.2 Voltages

[PTSOUNDLAB]

Hello,

does somebody know the voltage on pin 1 of 6922 in AudiNote DAC Kit 1.2 ? (Voltage A and Voltage B on attached schematic)

Thanks

Anode voltage for this SRPP configuration should be around 200V 180V will be fine. You don't need the 2k/2W resistor, so both voltages are the same. If you insist having 2k resistor than first calculate (or look the characteristics) the DC current through the tubes. Add this current with the current over the voltage divider (180V/200kohm), multiply it with 2k and you will get the voltage drop across this resistor.

Hello,

I'm sorry but the file is too big for your mails. You can download it here http://ptsoundlab.jexiste.fr/depotimg/kit12.exe .
I will remove it in one or two days, so download it now

Cordially

Pascal.

Why the file format is exe?

You can download from the link posted above.

It is a exe file because the archive is a self-extracting RAR

Cheers

Hello,

I have removed the file from the server because I have some troubles with the provider (too many people download at the same time ).

Dear webmaster, can you remove the link in my previous post please ? Thanks in advance.

Cordially

Pascal.

Hi,PTSOUNDLAB.Thank you very mach....
By the way,do you have any good dac schematics with PCM63P-K?
If you have could send it to me?
Thank you very mach...

Sorry to come in late PTSOUNDLAB, but could you email me a copy of the schematic if and when you have the chance.

I toyed with building a NOS DAC based on the AD chipset some time ago (not necessarily a copy of the AudioNote) but never managed to get it right.

I would love to return to this project, but have never found any AD chipset designs which inspired me, so I would be extremely interested in looking at the AudioNote in depth.

Would be very greatful if you could help.
