Just did my first vero layout...can anyone correct?

Original schem:



Can anyone tell me if it looks right? I've looked it over once, but it was a quickie cuz I needed to go to class. This here is my first attempt at a vero layout, so I figured I'd start out with something easy. I'm sure there's about 6 different layouts for this circuit out there already, but I'm not looking to do something new. I just needed practice right now.

Original circuit by Gus Smalley, by the way.

PS: if you're looking at the schematic, it took me a while to figure out whether or not the 47K and 10K resistors connect to the spot between the 22uF and 100K (near the bottom left of the schem). They actually DO connect.

9v/10k to collector is wrong, you have it passing throught he 100k 'FIRST'
Should be direct, through 10k to collector.
The 100k on the 9v rail should be "before" the 22uf cap from emiter and
Also before the 47k to ground .....

They are two easy moves.

For correct boost pot wire up :
Lug 3 from emiter and lug 1 is ground :
Back of pot lugs facing down, left to right    3 - 2 - 1

gotcha...for some reason, either fireworks or me screwed up and it's not saved as a PNG  so I may or may not correct it. Like I said, only practice.

Is there any particular/rechincal reason why that 100K needs to be moved before the 22uF and the 47K on the 9v rail?

Yes. it's setting up the bias for the base of the transistor, between base and ground is the
10k/47k , which is fed by a 100k off the 9v rail.
If you dont have the 100k "limiting" current, then it wont be the right bias for the tranny to
operate properly.
Because you would have 9v "directly' at the 10k/47k node 
( hope that makes some sense )

thanks, it's starting to. I'm learning, but I've got a long way to go before I understand why/how a lot of things work.

That's why it's groovy that you and RG and Mark and and all those other fancy-pants DIYers are patient enough to help people like me.

No problem , I have to say that I'm about 25 years of EE experience behind someone like RG !!! 

The details of "Why" still eludes me, I just know "what" should be connected ..... almost !

at least you've got the what.

I just started freshman year in college, and I plan to be an EE, but I'm doing general ed first, ya know? I'm stoked to actually GET electronics.
