Orange squeezer debug

[blizzard384]

Hello, i have problem with my current project: orange squeezer. Its my third project, but first where I had  find myself layouts, find right components and do PCB by myself. Other two projects were just kits. Please, also check my shop list, i dont know if i bouch everything right. Pcb seems fine, i can provide pictures if required.


1.What does it do, not do, and sound like?

Bypass works, when switch is engaged, led lights up but no sound at all. It does very quite cracking noise when pot is turned or bias adjusted.

2.Name of the circuit =

Orange squeezer

3.Source of the circuit (URL of schematic or project) =

http://www.tonepad.com/getFileInfo.asp?id=88

I also used wiring diagram no. 5 from same page.

4.Any modifications to the circuit? Y or N

No

5.Any parts substitutions? If yes, list them.

Here is my shop list:

1x Alpha Potentiometer 10k audio   
1x 6,3mm Mono jack   
1x Mini Trim-Pot 10k   
1x 1k5   
1x 2k2 metal film 1%   
1x 10k metal film 1%   
1x 82k metal film 1%   
1x 100k metal film 1%   
1x 220k metal film 1%   
1x 390k metal film 1%   
3x 470k metal film 1%   
1x 4,7 M metal film 1%   
2x 2N5457   
1x TS4558   
2x MKT 47nF      
1x MKT 2,2nF   
1x 2k4 metal film 1%   
4x Tantalum 4,7uF   
1x 1N34A

I made PCB myself.

6.Positive ground to negative ground conversion? Y or N

I dont think so.

7.voltage? =>

I wasnt able to find any 9v battery home, I was using 9v adapter from marshall (i think its stabilized)

Voltage at the circuit board end of the red battery lead = I didnt have battery, so i put black robe to ground and checked (9v) labeled solder joint and there was 9,11V

Voltage at the circuit board end of the black battery lead = I checked V between (+) of DC jack and ground labeled solder joint on circuit board and here was also 9,11V


Q1
D = 9,11
S = 0,14
G = 0

Q2
G= 0
S= 0
D= 0,0010-0,0008

Using this: http://www.musikding.de/product_info.php/info/p362_2N5457.html

IC1 (or U1)
P1 9,12
P2 0,823
P3 0,627
P4 1,2
P5 0,001
P6 0,001
P7 6,53
P8 6,53

Thanks for any advice, if you need any more informations, just ask.

Either you read the pins wrong OR you have your IC in backwards. You should read V+ (9.11V) on Pin 8. Not Pin 1 

Also, you should be reading V+ (9.11V) on Q2 Drain (or Source... too lazy to look up which)

Start with these and repost if you still have problems 

[blizzard384]

Thanks for respond.

I was getting reading for IC pin according to this picture: http://www.musikding.de/product_info.php/info/p378_TS4558.html

Also setting IC beckwards didnt change a think. (I can provide readings if you want).

I took some pictures, I am not sure if I have done everything right:

And please dont laugh at my PCB, I know it looks ridiculous.

I hate to say it BUT, something is really wrong.  

Your board should look like the one on the Tonepad pdf file and yours looks like it was reversed  

Print out the layout picture of the Tonepad board and set it side-by-side with your board and they do not match!!

Are you sure the PCB image didn't get reversed when you printed it?

You would need to solder ALL of the components and wires on the COPPER side of the board to correct this  

EDIT: After looking again, it looks like you drew the layout by hand from the Tonepad layout BUT, you didn't take into account that when you transfer the image it is REVERSED!

[blizzard384]

Thanks. What I did was that I printed layout from tonepad, duck taped it on circuit desk (on copper side) with printed side up (not to desk) and then with nail i made holes, where solder joint would go and then connect it with black marker... its that wrong? i was wondering if i was doing it right... but does it matter that i made it this way? Couldnt it just work this was or i @#$%ed it up entirely? Component werent so expensive (like 5 euros) so i guess i can buy new ones...

what i am asking is: is there i way to fix it or i should just start over?

Thanks

[Govmnt_Lacky]

You have two options.

1) Remove ALL of the components and wires to solder them to the COPPER side of the board (not advised  )

2) Re-do the board. This kinda stinks but it would be right! This time, when you tape the printed image to the copper you need to make sure the IMAGE SIDE is against the copper.

Thanks for your support, i feel like an idiot right now...

Thanks for your support, i feel like an idiot right now...

If I had a nickel for every time I have said that!!! 

Don't get discouraged. Try, try again...... 

[blizzard384]

Btw did I put trimpot right way? I wasnt sure about that position...

Thanks for your support, i feel like an idiot right now...

Don't feel bad. I did almost the exact same thing when I built mine, except I had designed my own perfboard layout.

After releasing the magic smoke from one of the fets a few times, I realized the error.

I will  N E V E R  make that mistake again. I bet you won't, either.

Good luck!
