Steever Posted June 20, 2011 Posted June 20, 2011 (edited) Hi everyone. I have a pair of each in the pre stage of my valve integrated. Since rolling in the 6SN7EH's and the GD 6SL7's, compared to the cheapy Chinese valves that were in there new(1pr of 6SL7's and 1pr of 6SN7's), I don't get quite as much gain. What would be suitable substitutes for both these valves that would provide just a little more gain. Cheers Edited June 20, 2011 by Winno
Keith_W Posted June 20, 2011 Posted June 20, 2011 Unless your valves have drifted off spec, changing valves should have no effect on gain.
