Y'know, I've started a few vero layouts (to benefit all mankind), I place half a dozen components then I think to myself "@#$% this @#$%ing mother@#$%er !! If people are 'individual' enough to want to use @#$%ing vero over a superior media they can just make their own @#$%ing vero layouts !!" I HATE vero with a vengence.

erm...perf? only joking.....

i'll get my coat..........

  funny...

rob has left the building....with his coat on....



i'll  put this on here on mr slaves behalf...to cover his rash.

A guy over at FSB just posted a pretty neat looking vero layout (unverifed), I'm sure he won't mind if I post it here:

FSB?

[BoxOfSnoo]

FSB?

Either front-side bus if you're talking about a computer, or more likely the other DIY stompboxes forum whose name we don't mention

Thanks guys,

I am having a little trouble with this circuit on the breadboard. It seems that my supply voltage, which is 9v volts from a One Spot power supply, drops down to 6.3v. I believe I have located the issue to be the 78L05 regulator. The one I am using is to-92 package and I am using the PCB layout as a guide for hooking it up.
Anyone have a suggestion to correct my problem. I am seriously excited to try this circuit as soon as I get past this issue.

[Barcode80]

I'm confused. the 78L05 should drop the 9 volts down to 5 (or 6 with tolerances). Am I misunderstanding your question?

[Pakaloabob]

Yes, the regulator does drop the voltage it outputs to 5 volts, but when it is in the circuit, my supply voltage to the rest of the circuit  drops down to about 6.3v. That means that the voltage fed to pin 8 of the dual op-amp (NE5532 in my case) is only at 6.3 volts when it should be 9. In addition, the voltage fed to the non-inverting input on one side of the op-amp is also not what it should be. 
Something is pulling my voltage down, but I can't quite figure out what it is. When I remove the 78L05, the supply voltage is back to 9 volts, when the regulator is in the circuit, it reads 6.3v. I have tried another regulator and also another PT2399 with the same results.
I just thought someone might have had a similar issue, or be able to point me in the right direction.

Sounds like you need to start checking resistor values and solder bridges on or around your voltage regulator. R1 shorted to the ground post of the regulator?

Good Luck

Well, it turns out all I had to do was run the circuit off a battery instead of a power supply. 
I really wish I knew why the power supply wasn't working properly for this circuit. If someone has any idea, I would love to hear. At any rate, things are working fine off the battery so I won't get too worked up.

just as a note : i had the very same problem with a 'zombie chorus' worked fine on a battery, but wouldnt 'chorus' on my psu...
i ended up having to put a regulator on the dc socket..and it worked fine...hope this helps....
