I need a PCB schematic for AlephP preamplifier,if have someone or know, where can i found please e-mail me.
Thanks for the help.
i would like to have a schematic for the P1.0 volyme controll otherwise i will havto draw it myself....=((
Give me the compos reference of your Aleph (the most precise you can have)
Give me your demension, your philosophy (1, 2 boards) with power separate or not
I made it.
Come on... I have lot of time. And the formation...
Sorry I would say that I make the PCB on what scheme you want.
I want to participe at the effort of the community.
I'm so impetuous...
http://www.passlabs.com under download...make an layout for the relay control circuit for the P10 ........
it would probobly be a waste of time to make one for the relays since alomst everybody will use different kinds.....
so..how good are u drawing layouts? ...
Thank's for your effort to help me and others!
I need the PCB only for the (alephP 1.7) preamplifier part.
The dimension not so important,if you can, do short as posibile the circuits.
Oh i forget it, the output caps i would to use are 27mm long
and 19 wide.I will use 2 for output (paralell) and 1 for input.Another components is as usual 1/4w resistors i use.
Thanks again your help and waiting...
I know this idea will have succes.
But please, be more precise.
If you want to me make a PCB, send me a mail with attached the schematic and the max precise will you want. (size and referenc of your parts, the general placement of your modifiable comps...)
How good I raw layouts? I'm a newbie (19 years) but a professional. I make PCB long the years in school.
The most difficult thing is to get libraries for the components or to make it, so I need to see the composants send me the max info you can.
I think the big wokrs begin now for me (Sigh!!).
Victor - I'm just downloading Aleph 1.7, I study it and I make a first try. But continue to send me more precise infos.
uuuhhhh for your mods send me a draw, this more efficient than a long discuss. (You say to me input and output) and I don't know that we are the same conception of electronic, I'm a professional that don't have the habit of audiophile.
Hifi - Send me a mail, I don't know the P10 so when you talking to me about relays ??? I must to see the schem before. Promise I will get him. For the moment I'm concentrate for Aleph Preamp (for victor) one thing by one thing.
Be patient everybody.
the p1.0 the predecessor to p1.7...but nevermind im drawing my own layout...i couldnt wait =)) thanks anyway...
btw witch program do u use?
Alpeh P 1.7 PCB drawing
Big schematics isn’t it? (Aleph P 1.7)
The difficulties is to bind the different ***** and to construct form the existent implantation the left side of phonic part.
So it will be take me more time than expect but I think that it is makeable.
But when you say "the caps on the output", the output of what ? ?
I'm use for technical electronic it's an engineering works but the audiophile DIY seem like... cooking. I will learn a lot here.
- Victor for Aleph P 1.7 PCB draw
* One question: on Aleph P Motherboard I think that +REGULATED is bind with +50V of the power supply, do you think so ? (It’s Right?)
* The caps who you give me the dimension are the Q27<->Q30 ? Yours have the same dimensions of the past implantation (in diameter)?
* I prefer vertical position for the transistor (like Q23 Q24 Q22…), that made more dissipate, your advise?
* Do you wish to put some little caps in parallel of diodes bridge?
* What’s the style of switches (SW1)?
* What’s the exact reference of Thermistor TH1?
* CHA(-IN,+in)CHB(+in,-in) can be bind with +output –output +input –input, it’s right?
* What sort of relay was used for Relay1-8A and for RLY1-16? I think they must be the most quite as possible (you too I’m sure…).
Holly **** they are two side! For the motherboard only one side was shown.
Wow ! ! The Pass parts placing is good looking. Sure I will copy it (Do you forgive me ? But it’s really good) Ouch ! ! With this schema my Iiyama 17’’ seems to little. I forgot a side ! ! What a sugar I make J
*For the two side of the motherboard I think that de R73 spray the +50V to the two side, and that one of the C25 or C26 goes to the left side.
* The switch for gain choice. Do you need it? How do you want the switches or switch? (SW1)
* The optical interrupts, nobody have more precise?
Hifi – I use P-cad, with this I must write the schematic, it make a net list which place component on the Pcad PCB, and finish my work.
