Hello everybody, I'm new to vintage audio and I found this forum being very usefull! I would appreciate some help on setting DC offset on my 771. I found that my right channel has some distortion, so by reading on this forum, I tried to check and adjust the DC offset. The left was approx between 2 mV and 12 Mv. The right was approx between 50mV and 60mV. I say approx because the read my multimeter is giving to me is very unstable. I succesfully adjusted the right approx 2 - 12 mV, but I can't get a stable read. I have a cheap mastercraft numeric multimeter and I didn't touch the bias current adjustement yet. Can someone tell me why I can't have a stable DC offset? Thank you for your help!
