Hey there fellow La Figaro owner. I have the exact same problem but only in the right channel. Looking through your pictures I see that we have the same model but I can´t see what wires are not connected. Which one was it for you. Maybe I have the same problem, I just can´t see it?

I have been following this thread with great interest over the last year and I finally recieved my La Figaro 339 via Massdrop two weeks ago. Sounded great with stock tubes but started to sound fantastic as soon as I put in the 5998 power tubes and 5693 red hots. Then weird things started...
