I would use the right part, but it will not explode if you use 47n. Your choice.

Thanks Peter!
I'll try 47n and we will see if it works or not
cheers,

Hi again Peter,
last questions and I hope if you have a bit time you can save me...

1- I must cut the two traces?

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!

 

[peter purpose]

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,

 

[peter purpose]

any one didn't use the sowters for their build?

As far as I know we all used Ed's.

 

[jandoste]

Good news They sent it me...
Now I got the colour codes but I am not sure about +/- which colour?
any advance?

Thanks

 

[peter purpose]

Try this... or the exact opposite.

 

[jandoste]

Merci beaucoup Peter

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...
- more two questions;

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?

Thanks

Ok, It was not easy this build for me but I am finishing it[ slowly:]
Ok here my calcule and I just need it's right or wrong...
I used:
5 green LEd :2.2V
2 yellow: 2.4v
3 red: 2.1V
So it was wrong 47ohm! and It's must to be 1k 1W?
if I am not wrong?
any idea?
Thanks

 

[jandoste]

Ok, I'm not a good home worker

 

[peter purpose]

You're talking of RM1? Stick 1k5 in there. 1/2W is plenty.

 

[jandoste]

RL 1 and RL 2

 

[peter purpose]

It would help if you mentioned the parts you are talking about.
Stick a couple of 2k2 in there and be done with it.

I put there two 2k2 and no chance :-[

 

[peter purpose]

No chance of what?

Sorry, I meant the leds don't  work...
