Tube Screamer - Doesn't Work - Debug Help Requested

[slacker]

The voltages on the first transistor, I assume this is Q1, almost look like it's in backwards. I would check this, it should be oriented the opposite way to Q2.

Do you get any sound on pin 1?

No sound on pin 1. Only 3.

I just completed a tonepad tube screamer that works properly. I can post my voltages if anyone thinks it would help.

That would be fantastic!

Thanks, the transistors are in fact facing opposite directions. ie the one curves toward the pots, and the other curves toward the bottom of the board opposite of the pots.

See if you can upload high-definition, well-focused pictures of both sides of the board. Keen eyes might be able to spot either misplaced components or potential problems with solder joints.

It's bad guys, I'm sorry. My soldering iron is a wood burner... with a soldering tip.... yeah. A proper multimeter and soldering iron are on my list of things I need. But currently, it's the only I have.

From those pictures, both transistors appear to be in backwards. In http://imgur.com/a/RQJ5E#4 you can see what the orientation of the transistor on the right should be under the socket.

Fixed. 

Still can't get audio from IC pin 3 to IC pin 1. All I get on pin 1 is a little static. Maybe the IC is bad? Is there a way to test for this?

I'm sorry angelkiller, I didn't see that you wanted voltages. I'll post them later tonight.

Ok, here are my voltages:

Supply voltage is 9.50V

Q1 (2N3904)
E  3.58
B  3.83
C  9.50

Q2 (2N3904)
E  3.58
B  4.03
C  9.50

IC1 (JRC4558D)

1  4.70
2  4.78
3  4.71
4  0.00
5  4.69
6  4.66
7  4.65
8  9.50

I hope this helps!
