Sadowsky bass preamp problem,pls help!

[ppanousos]

I made a veroboard of the sadowsky bass preamp and i have a problem.First of all i triple checked the placement of all the components and they are correct.Second i don't think i have cold solder joints (all look ok and shiny) and i don't have any bridges.The voltage at the drain of the tranzistors is 5v.The problem is that i only have signal at the output when i touch the back of the vero with my finger.Any thoughts?Thanks in advance

For the peeps here to be able to help you out, you should at the very least:

1) post the schematic from which you made your build
2) post the layout from which you worked
3) post the photos of the actual build you made
4) compile all the relevant voltages and readouts

and most importantly (read "The Manual"):

This is the link of the layout i worked on:http://tagboardeffects.blogspot.gr/2013/04/sadowsky-preamp.html.Here are some photos of my build:

I put two 2K resistors in series with the 10K resistors that go to the drain of the tranzistors to obtain the 5v.Also i did not have the 750Ω so i put 500Ω+230Ω.Ι did not wire the bass and treble pots yet.

Ι did not wire the bass and treble pots yet.

The signal passes through the treble pot, without it in the circuit you won't get any sound out of it. By touching the back of the board you must be making a path for the signal.

hard to say anything, the schematic link is wrong..
