1176 rev d problem

[Chrys]

Hi all
I just finish my 1176 rev d but seems it doesn't work at all
when I go to calibrate the r44 doesn't move the vu metrer
One of the strange thing I noticed, when I turn up the out pot without any signal the vu meter goes to full scale +3
and when I try with a signal on it seem it works only in and out pots without any kind of compression
so the attack and release don't change anything
I already check the wiring and the components placement/value, but nothing...I'm going mad :-[
Could you please guys help me ?
Thank you so much
Chrys

Grounding the chassis and XLR's?

 

[Chrys]

Hi jwhmca
yes I did it even if I did't check with the multimeter
do you think this could be solve the problem?
Thanks for the help I'll fix it

 

[Chrys]

Done!
Ground is ok ...but still have the same problem :- :-\

 

[jwhmca]

Do you have a scope? Check signal path? Lots of noise on the output?

Sounds like you have a bad component in the path somewhere. Did you check and measure everything before soldering to the board?

Another possibility is you have something wired wrong

 

[abechap024]

check you in/out wiring and how all your switches and pots are wired.

First of all thank you guys for the great support and help
this is exactly what I was thinking about Aaronrash, a bed component somewhere...
When I can I will check the voltage and try to find the probs...
and sure Abechaop024, I will also chack again the in and out wiring
Jwhmca, I don't have noise on the out, I've got it only if I put the out fully clockwise ( and the meter goes full scale) and the input in the mid
Thanks again guys I'll let you know asap
