Hi looking at DAC End 2 - the AD1865N-K with single ended vacuum output stage and the measurements in particular. 2.67% THD??? Is this right as the original DAC End measures well under 0.1% in all measurements.
Hi, can someone advise me if these transformers will work design old end dac salus shunt for DAC. I understand I need 9/12 volt 300ma x3.
10 v center tapped

Any other suggestions of where to get such power transformers i the USA. For the I/V power supply I found a good 250v and 9 volt from Elcor, but cannot seem to find these 9/12v transformers easily besides those for lights. Would it be necessary to use a better quality audio transformer here?
thanks, John

I made a run of power transformers for the Salas shunt regulator and still have three of them. They are six 9 vac @ 200 ma windings and are heavily shielded to cut airborne radiation. A number of folks now have them in use. PM me if you are interested.

I asked in another thread and I´ll ask here to.
Quanghao😀o you still have the old I/V stage boards for sell?
Or if you have the new I/V board I can use that one.
Or if sommeone else have a spair they dont need.

Has anyone physically separated the ground trace between the ANA and the DIG on the older Dac Board PCB and reconnected it similar to how the new one is, referencing the connection diagram?
Hello!
I'm studing the electric diagram of DAC End 2. What is the voltage of anodic if i use the 6DJ8?
Antonio.
P.S. Excuseme for my English!

for 6DJ8
+ B= 250 V
V anode = 90V

Hi Quangao!
Thank you!
Excuseme but i believe that i don't understand.
In this picture of Dac End 2010 + B is 200 volt, isnt' it?

Maybe i have got wrong...please can you help me?
Thank you .

Thank you Quangao!!! Now i'm sure! 🙂
Please can i write you in private?
Best regards.

What is the purpose of paralleled 220ohm resistors in series with the grids signal(on the tube output board). Could I use one 110ohm of high quality instead?

Quanghao,
I'm trying to order some PCB boards but I cannot complete the checkout because it says "There is no carrier available that will deliver to this address! "
. Shipping is to Australia. Please let me know

Well, you are welcome but .... can you send me paypal request or something? Perhaps I would like to purchase those items.
Hi Qhanghao!
I have a question to you. I''m building the Dac End 2 : i would use the 6DJ8. In electric diagram there is a 6 resistors of anodic: R16, R17, R18, R19, R20 and R20A while in pcb there is R15 too. Must I solder a 47K 2Watt resistor also there? Or not?
Thank you.
Antonio.
