Is this stripboard layout ok? (Fonik Attenuverting Mixer)

[funtykigs]

I'm a total newb with laying out boards.. I've made plenty of kits and I know a little theory but this is very new to me.

Can anyone tell me if this layout for the power section of the Fonik Attenuverting Mixer is correct? (I've not powered on yet as I have some questions)



I'm basing it on this version - http://www.modular.fonik.de/pdf/f-mixer-rev3.pdf

I have a couple of questions.

1) Where does that ground from C5 & C6 go?

2) I'm confused about the Zener Diode section, its producing +5v which I assumed was to normal the inputs... but they are +7.5v on the schematic

Any help would be great

Use the same common ground, like this, and you should be good to go..

Cheers guys. It's funny how a little knowledge is a dangerous thing At least it stalls me rather than me making wild assumptions

ok so that circuit seemed to work, I've now tried out the section with the Zener Diode..



I'm feeling dumb again though... how can I meter +5v on this circuit?
I can read 15v across the points I would expect but can't get a +5 reading anywhere

dammit, that's what happens when you do this at 1am



see with it like this, across the zener diode I'm reading a value of around 2.5v which is constantly falling.. and again nowhere am I seeing 5v
