First! Say Hi! to Mark Houston I'm here now... Can you remember me??

My ZCA is here

I choose only audio grade if i can. That make sound really good! I come with softly,Big sound stage,musical friendly,etc...

My component
Ri/p - 1K >> Allenbradley
Rg - 1M >> Dale
Co/p - Nichicon KG 6800uF + RIFA 10uF + Mustard ,, Yeah that Tri-cap
Ci/p - Mundurf M-cap + Mustard ,, Bi-cap
Cg - ELNA RJH
Cfilter (onboard) - 220uF Nichicon FW + WIMA

I usually ask BI-CAP or TRI-CAP at INPUT or OUTPUT. Cause by do that sound better than one component . and PSU doesn't finish now i had waiting for a big capacitor


You should listen from L.CH my phone are crazy with R.CH


In this video i finding a lot of part to make PSU in my house and i found RIFA>2200/100*4,Samwha>10000/100*1,Nippon>10000/100*1,CHOKE 5A *2,Transformer 18-0-18V *2 ,Diode FE5D *200 (OMG! I had that diode a lot but i had never use it for a year) This diode use in Gaincard...

OK make it.
TRANSFORMER > Diode/Full Wave > C2200*2 > Choke > C2200*2+10000*2 > ZCA
Yeah! sound nice but it will be better if my huge capacitor available i order HUGE MALLORY and HUGE PHILIPS which rate 55,000uF for 6 capacitor!!!!!

Most of the time simple is better.

Good job you have a very clean layout and the PCB looks great,

Keep us updated on the PSU :D

Hi taoybb, nice work. How do you like the sound.

Can you also post the PCB files so others can make the board.

Cheer and welcome to the forum.

Hi tayobb,

nice PCB - well done ;-).

BTW - how did you create the imprint (silkscreen printing) on the component side of the PCB.
Do you know a DIY way to print the component sides without a real silkscreen (without using ink and squeegee).

I'm just curious :-).

I once tried toner transfer but it did'nt work for me. Tried photoresit and it works perfectly. It is very easy to do once you get the hang of the process i used paint but there are films an even photosensitve spray ;)

Thank to everybody! For post


Silkscreen? I dissolve a PCB Maker company name "Innotech PCB" . So in thailand PCB made very cheap! This one cost about 18USD >> 4.5USD for Film Artwork / 5.5 For PCB / 6.6 For silkscreen "PER 10pcb!" <No problem there're Group-Buy a lot! Save money!> / and other for shipping

*** Screen if over 10 of PCB it cost will be 10USD with NO LIMIT OF Screen! That sound great!

But one problem is Screen Template that i sent to company! it bad quality, If template are better screen will ba more beautiful and sharper. That OK i don't mind that.

If you can share a PDF or the .BRD files, I can add them to the main project page.

Cheers
