I laid out an Orange Squeezer for vero/strip board.
Can some kind soul confirm? Gratsi!

If you post a link to the schem I`ll have a look at it.
Thanks! LOL I assumed everyone had it memorized!
Here's two links, one for a PCB layout, and a one for a schem:

Oh, and here's a link to Tonepad's PCB/schem. (http://www.tonepad.com/getFile.asp?id=88)
Do you have 2 jumpers in the same hole at pin 4? I yes, ok cool... if not, your IC's not grounded.
Yeah, that long white like is actually two jumpers: one from 3 to 4, one from 4 to ground. Two wires are going into the hole connected to pin 4.
Good eye!
Ok, I've revised the layout, to use less board space.
I've eliminated 5 columns.
Still valid?
Jeezus, I`d just finished checking the last layout. Give us a chance ;D.
For the record I couldn`t find any fault with it.
The revisions have confused me. Where is C3 going? Shouldn`t one of the jumpers be going from the base of Q1 to the emitter of Q2?

Ah, you're right.
The jumper from the top row to ground needs to be LEFT of C3.
And Q1 and Q2 are connected with the jumper that goes from vr 1 to vr 2. I should probably move that jumper.
Ok. Rev 3... I think I've fixed it...?

Here is the layout I drew off of the same schematic, clik link above, and mine works perfect, for a reference.
Ok gents. Rev4. Still looking good?
Changes are:
- realized I was jumpering something in the wrong place
- wanted to get all three contacts for the trim pot to be adjacent
- moved the IC's jumpers; I had them in the same holes as the pins which is dumb, considering there's free holes left of the trace cuts
- removed another column! I want to get this layout as teeny as possible
Anyway, I went over it and it looks ok to me...
Edit - .5 rev
- rotated r6 and moved c5 down to the bottom, so i could move a bunch of components over
- c5 sharing holes with r2 & r3; the waste of a column was bugging me
Both these changes eliminated two entire columns!
This layout measures about 1.5 x .7 inches!
That's smaller than that Tonepad pcb (which is 2.5 x 1).
Rock on! I've checked and checked, and it appears good. I'm changing to version 1.0.
I'll be building it soon, but would love if other people wanting to build an Orange Squeezer were willing to give this layout a shot!
i'll give it a shot when my futurlec order with my stripboard in it gets in my mailbox which can either be tomorrow or in 2 months.
I was wondering about the layout of the IC. Since it seems that they're using pins 5,6 and 7 why are pins 1 and 2 jumped together and pin 3 grounded along with pin 4?

I wish I knew enough about electronics to answer that question!
They do it on the Tonepad schematic, and on MarkM's PCB layout posted here.
I think it's to keep the Flux Capacitor from overloading ???
just wanted to ask if your layout is verified
