Building a symmetrical PSU B1 buffer

[Ryssen]

If it is PDF let them know the exact target dimensions as given by Crt.

Ok,what is it?
60mmx115mm?

 

[Salas]

Crt says it all on post#41.

... and one

Thank you for doing the work. Add one to your list for me.

Salas, can you send me the EAGLE files ? I want to build one, too.

@ LaOde... thanks for sharing and the PCB works, permisi mau ikutan bikin PCB nya ya bro

hi Ryssen
yes the PCB dimension is like i wrote in post41

about the Eagle Files, not include connection mark ( like input, l-pot, r-pot etc ) those letters only in PDF file.
and my eagle files (layout) is very 'tricky'.
i use 2 layers for bottom layer.

thank's for the effort to make a group buy.


@Surya
dengan senang hati pak.

You got mail.

So it´s better to use the pdf file then.

one (1) board for me!!

salas can i use 2 b1 pcb to make balanced b1?.
thanks

 

[Salas]

I guess you can, I did not try it though.

ANYONE HAVE BEEN BUILD A BALANCED B1 BUFFER? ..

 

[Floric]

yes, according to the zm-version several pieces

they work excellent

edit: sorry, i built the balanced ps version. a friend of mine built a symmetrical one consisting out of two b1 per cannel. works too

regards

GB still open?

Is the group buy still open?

And is there any indication on pricing ?

Thanks!

[grufti]

For the group buy go here. Pricing was quoted some time ago for fewer boards and still a slightly different layout. It was very reasonable.

Ask

Hi all, new member here.

I want to ask, is it okay to use resistors which is valued +/- 5% on its original value in this project? Because i have some resistors (metal film) with uncommon values, such like:
464 ohms --> substitutes the 470
215 ohms --> substitutes the 220

I want to build this thing too. But since i'm a really little poor guy now, i dont have much budget. I want to use as many components that i already have

Thanks before.

Hi,
+-1% resistors are close tolerance.
Most circuits will operate with +-5% tolerance.
The B1 will work with this wider tolerance.

@AndrewT: Thank you Andrew
