Rocktave PCB error

[Mark Hammer]

Bit by bit, I take care of the backlog of projects.  Tonight, as I was throwing some pots and jacks on a PAiA Rocktave board to get it ready to install on a quick and dirty multi-FX floor unit intended to work like a sort of alternative Microsynth, I noticed an error in the PCB pattern that is included with the scanned article found here: http://hammer.ampage.org/files/rocktave.pdf

I had retouched the scanned PCB mask accompanying the article so that folks could print it out and use it to make a PCB.  It would seem that in the scanning, and retouching, I included a bridge between two traces that shouldn't be there.  And it only took me 7 years to notice!!

C17 is a 100uf decoupling cap between V+ and ground.  The way the PCB mask is drawn shows a direct path between V+ and ground directly under where C17 goes.  I think you'll find it works much better when V+ is not directly tied to ground.  Not only that, but the batteries last waaaaaayyyyyy longer. 

Note that this error applies only to the PCB pattern in the article and NOT to Dean Hazelwanter's other layout, linked to from GGG.  My profuse apologies if you attempted this and it had you stumped all this time.

Ooops! I see it. I was actually going to build from this a few years back, but went for a modded Blue Box project instead. That bridge is something I probably would've caught when soldering the cap, but who knows?
   Makes me want to give this one a stab again.... really love octave down effects more than the octave up variety.

Another error discovered in the scanned article....

C10 is shown in the picture as having its + side going to ground.  To paraphrase comedian Kevin Meaney "That's not right!"  The - side should go to ground.
