[SOLVED] -> jumpers J5 and J6 missed, see below

Hello everybody,

I have just received my Legato 3 (no buffers) and finished soldering. Some parts have been upgraded: 180R resistors for 2V output, Silmic II caps (same specs as original ones), 1K and 100K resistors have been upgraded with PRP´s as well.

Powering is done via 3 placids, the same ones that were powering my Legato 2. Output is set to 14.75 volts.

Reading the manual, I was able to correctly set balanced outputs to 0 VDC with VR1 and VR2. Now I am trying to get 0 VDC as well for the SE outputs which measure almost 4 VDC. The problem is that VR3 and VR4 has little impact lowering the DC output so I reach the end of the pot when I am at 3.6 VDC. There is no way I can get 0 VDC at the moment ... anybody has an idea what I should check ?.

I can only use the SE output and have no way to check whether the balanced output has any sound at all. Any help will be much appreciated.

Here is a pic:


Best regards,
Pepe

Just two questions:
1. Did you install jumpers at J5 and J6?
2. Are resistors R25 and R26 required if the buffers aren't in use?

YES !!!!

I had missed jumpers J5 and J6 !!!, they are soldered now and.... gorgeus music !! , super gorgeous music !!
(what is the purpose or leaving those two jumpers unconnected?)

Thank you very much to Narla and of course Russ for your help guys, i love this community.

Special thanks as well for the team of Russ and Brian, your guys rock keeping the community enjoying and learning with your great products.
