Hi Basile,
So, you can only adjust 4 of the 8 tubes. In fact, I adjusted V1 to be 65mV but V3 then measures at 77mV. Do I then tune down V1 so that V3 falls within the advertised range of 57mV and 73mV?
Anyway, I found out that my VS115's right channel is causing my speaker to crackle (noises within the hiss), quite noticeable even during the day time. I even swap all tubes between right and left channels. The crackling still comes from the right channel. So probably not faulty and bad tubes. I tried all sort, changing power cable, use different sockets in my house. With my Jeff Rowland, no crackling just very low hiss.
Anyway, it is going back to the dealer, a 5 hours round trip though.
