First Amplifier - comments my BoZ Pcb please.. :-)

[darkstar666]

Hi to all, thi is my first post.... and my first project.

I'm very newbie to diy audio and so i decided to build a simple amplifier, the Bride of Zen preamp....

the board has a slightly modified layout, because i have some of 16x10 eurocard PCB cards available., and i've added both a resistor and a connector just after C1 to power up two LEDs (not in the drawing), one for on/off activity and one for current input selection.

how do you think about the layout? and may the added resistor require changing mains fuse ratings?

thanks in advance!

Hi
I like the look of you BOZ PCB I would be very interested in making this pcb would you let me have a copy of the pcb files and parts list
Thanks

i send u the pcb files and schematic written in Eagle.

i've reutilized some of the components (expecially the poly caps) i've at my disposal at work. the caps are 250v rated, instead of 100..

R4 is a 4w 2.2kohm resistor, to power the two Leds.

the connectors are all wago-style connectors, step 5.08 mm. the rest of the components came from he original document at www.passdiy.com


and the size of the card is 160x100 mm.

keep me informed!

You cannot open v. 4.13 files with v.4.11. Go to http://www.cadsoft.de and fetch the update. You just need to install it over your previous version. Of course if you are running a illegal version you are screwd.

Hey Darkstar

Any chance I could have a copy of this as well?

Cheers

ok! i send u the files containing PCb and circuit, and the PS export of the board (copper side)

remember i've not tested this board yet! probably i'll start the construction tomorrow or so...

i upgrade the fuse rating to 160 mA slow-blow, but i don't know if it's a good mod...
