Hi again Peter,

2- I am using the sowter 9935 trnx and I read again all thread but didn't find any info for wire connection :-\...

Do you have any idea?
and big thanks again Sir!

 
1. yes.... as per the instructions.
2. I've no idea of the colour codes on the Sowters.
They usualy print them on the reverse of the invoice.

Thanks Peter,
They didn't send me the colour codes :(... I sent an email them and any one didn't use the sowters for their build?
Cheers,
 
Hi Peter,
finished :) but  I guess I got some bugs with my build. if you have a bit time for helping me I'll be very happy man!
- Fist; the LED meter is not working [ didn't do the calibration]
- Comp and Lim don't work [ or just calibration problem ]
- More & Less don't...

I don't know if I wired on the right way for the att but something wrong:(
Merci
 
The two you have marked as 10k are probably too high. Measure your led and use an online led calculator.
R63 is indeed 150R, but you can leave it off for mono.
Meter board 12 to 12... you're just putting a switch in the path.

Most problems with these are down to the wiring. Check your work again.

Thanks for replied Peter!
I changed the resistors and I put 47r 0.25W and I already wired between 12->12. :-\
I used three colours maybe the problem comes by this way?
