I saw a You Tube demo clip of a Marshall 1987x reissue and it was providing some serious distorted tones with the volume at 4. I need to get to 6 or 7 before things really break loose. Right now I'm using Svetlana power tubes and Tungsol preamp tubes. Could a change to different tubes make that much difference and if so could someone recommend which ones to try? I haven't biased in a long time so I don't know where that stands. Could the bias also make that much difference?
Thanks in advance for the help.
