Fuzz Face Problems

[maurice]

I breadboarded a Silicon Fuzz Face today (from Small Bear).  It went great and sounded wonderful, but when I moved it onto a veroboard it doesn't work.

There's a very, very faint sound of something, but nothing any good (or like my breadboard)

Below is a pic of the layout I'm using.

Can anybody suggest any obvious problems?  I'm at a dead end



P.S - It's also my first attempt using DIYLC software

Just some thoughts:
1. Check the orientation of your transistors (mine would be the oposite of what is shown in your picture).
2. Check the orientiation of your electrolytic caps.
3. Check your vero board. In my opinion they're not very forgiving. So, look closely for small cuts (if you cut your veros with a knife it's easy to slip). Also, run a knife between all strips to make sure you haven't shortened anything when soldering.

Another thing: you have C2 and C4 in series. Is that what you intended? The schematic I am looking at have a 22µF there and yours would be 5µF, right?

Getting from the breadboard to a working layout of your own is a steep jump, but doable with a relatively easy circuit like this. Have you bought a meter yet? You should have one for troubleshooting purposes.

Start with a clean copy of the schem from which you did your layout. Set your meter for continuity. Go through the schem and make sure that Every point that is supposed to be connected to something actually is. Mark off with a yellow highlighter as you work. Are you sure that the connections to the jacks are going to the correct points? If you are persistent and careful, you'll find your bugs.

It's best if you go through the pain yourself, especially since you are starting with a circuit that you know works. Let us know how it goes.

Problem fixed!

I did several things:
1) Cleaned up the gaps inbetween the vero
2) Re-soldered any suspiciously 'bad' connections due to my bad soldering skills
3) Checked components with meter

It's all working fine now, thanks folks!  I think however the main thing I learned from this is to sleep on a problem rather than staring at it late into the night

@Pettol - C2 & C4 are substitutes for a 22uf cap I forgot to order.

[Pettol]

Great!

I figured. But shouldn't those be in parallel?

Capacitors in parallel? Would that make a difference... Does that mean im only using essentially a 10uf cap?

Either way it still sound good. Should i rewire?

[Electric Warrior]

You wired them up as a 5µF cap.

The caps are wired "incorrectly," but if it sounds good, I'd say leave it!!

I totally agree.

@maurice: tip:

when doing vero layouts, turn it 90 degress....

have top rail 9v...

bottom rail ground...

its a better way to start off as most schematics are the same ok......

glad you got it going!..

use for caps in series or resistors in parallel

Thanks yet again folks.  Out of interest, how would the sound change with different value caps (eg 5/10/20uf)?

[deadastronaut]

socket them and see.....,probably bassier the higher....
