Hi all!
Now i have some coment for PCB DAC-ash
CCF50
Vishay Dale

All resistor for the DAC
no 200R Cadoc
price: 10$ + 5$ shiping an free paypal!
Thanks!

hi! you can see the Data!

Hi Quang Hao,

I see the data sheet, there are 1% and 5% resistores,
but what you will send, the 1% or 5% Qaulity???????

Klaus

i measure it I show 1 to 2%

R40 in the BOM is 680ohm and on the PCB its 560ohm. Which is correct?

that is for led , you can use 500 to 680 R

Ah cool. Thanks quanghao.

Hi Quanghao Oscon 220uf x 12v will 10v be ok in i/v c18,21,24,26 thanks

Hi Quanghao Oscon 220uf x 12v will 10v be ok in i/v c18,21,24,26 thanks

yes! that is fine
C3,7,11,15,19,26 6.3 min V To 10V is ok!
and C25,27,29,33,35 min 47uf/6.3V

What transformers are people using for the DAC END?

 

[morpheous]

Hi Quanghao,

which type (brand) of connector use for ac1-ac6 input

Quang Hao,forOscons 220uF I can use 270uF

Hi Quanghao,


It's ok IRF9540NPBF-ND and IRF540ZPBF-ND ?

yes! you can use it!

 

[morpheous]

Hi Quanghao,

but I don't need a specifications for the transformer but I need a brand for the connector of the input (AC) and I need to say if the IRF9540NPBF-ND it's ok or i need to use IRF9540 ? Because in the boom list there are IRF9540 but from digikey or another distributor i find only IRF9540NPBF-ND the same question for IRF540ZPBF-ND.

Would the R-Core cover both DAC and I/V stage? or I would need another one for the tube I/V stage?

RF540ZPBF-ND ~IRF954.All is one!

R80-36 primary (0-110) x 2 /SCN: scondary (260-230-0-230-260)(90mA),
2.5-0-2.5(3A), 3.15-0-3.15) X 2(3A)

Iv use tube
You use Centre tap 230-0-230 to Hv supply.
you use + 2.5 +3 v for filament

Hi Quanghao,

I have Toroid Transformer T120 120W 0-200-260-300-360V(100mA)x2 6.3V(2A)x2 5V(2A), can use 6.3 + 5 =11.3V for filament or is it too high ? Also, can we replace R11 470Ohm 5W with power inductor 10H ?
